What Cannabis Sativa SUBSP. Indica Top does in the body

An unapproved plant used for pain, nausea and muscle stiffness under state programmes.

The body already makes its own cannabis-like signalling molecules, which nerve cells release backwards across a synapse to tell the cell upstream to quieten down. THC is close enough in shape to hijack that system, but it arrives everywhere at once and stays far longer than the body's own version, which is switched off within seconds. The result is a broad, indiscriminate turning-down of neurotransmitter release across cortex, hippocampus, basal ganglia and cerebellum — which is why the effects span mood, memory, appetite, coordination and time perception rather than any one of them.

What happened in people

Standardised cannabinoids produced small improvements in pain and muscle stiffness, but only four of 79 studies had low bias risk.

Words this page uses

Four words worth knowing first

Chosen from what this page shows, with each one explained before the word it depends on.

Stand-in result

A stand-in result is a number measured because the real result takes too long.

A picture of it, and where the picture fails

It is like judging a journey by the speedometer rather than by arriving.

Where that stops being true. Speed does predict arrival. Many stand-in results do not predict the real one.

What people get wrong. A stand-in result is often reported as the result itself.

A surrogate endpoint substituted for a clinical endpoint, valid only where the substitution has been shown to hold.

Randomisation

Randomisation means chance decides who gets which treatment.

A picture of it, and where the picture fails

It is like a coin toss deciding the groups.

Where that stops being true. A coin toss is fair once. Fairness here comes from doing it for everyone.

What people get wrong. It is thought to make groups identical. It makes them similar on average, including on things nobody measured.

Allocation of participants to arms by a chance process, so that unmeasured factors are balanced in expectation.

Absolute difference

An absolute difference is how many more people in a hundred were affected.

A picture of it, and where the picture fails

It is like counting heads in two rooms of a hundred.

Where that stops being true. Heads are easy to count. Study results carry a margin of error too.

What people get wrong. It is confused with a percentage change, which can look far larger.

The arithmetic difference in event rates between arms.

Confidence interval

A confidence interval is the range the true answer is likely to sit in.

A picture of it, and where the picture fails

It is like a weather forecast giving a range rather than one number.

Where that stops being true. A forecast range covers tomorrow. This one covers what the study could resolve.

What people get wrong. The middle number is read as the answer. A range crossing zero means no change is still possible.

An interval estimate that would contain the true parameter in a stated proportion of repeated studies.

What was measured, goal by goal

One row for each goal a registered study measured something for. One column for each kind of thing that could be measured.

Registered studies list 40 outcome measures that RNAWiki could read. A registered study says what someone planned to measure. It does not say what they found. 0 of the matched studies tested this substance, and 0 posted a result.

There is no single score. A strong test result and a weak life result are different facts.

What it changes in the bodyRead from sources, not yet reviewed

The path through the body

From what a person takes to what changes. A solid line is a step measured in people. A dashed line is a step nobody has measured that way.

  1. Start

    Cannabis Sativa SUBSP. Indica Top

    What a person takes: Inhaled flower or concentrate, oral edible, oral oil, topical preparation.

    The measurement behind this step

    Route changes the drug substantially. Inhalation delivers THC within minutes and gives the user rapid feedback on dose. Oral dosing takes one to three hours and produces 11-hydroxy-THC through first-pass metabolism, a more potent CB1 agonist than the parent — the pharmacological basis for the well-documented pattern of accidental over-consumption with edibles. Concentrates raise the delivered dose per inhalation by an order of magnitude over dried flower.

  2. Getting in

    Inhaled, or eaten and converted into something stronger

    Inhaled, it reaches the brain in minutes. Eaten, it takes an hour or more and the liver turns it into a metabolite that is more potent than the original — which is why edibles behave differently.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    Inhalation gives peak plasma THC within minutes with bioavailability of roughly 10 to 35%, highly dependent on inhalation topography. Oral bioavailability is about 6 to 20% with peak at 1 to 3 hours, and extensive first-pass conversion to 11-hydroxy-THC, which is CB1-active and crosses into the brain readily.

  3. Reaching the cell

    Distributes into fat and comes back out slowly

    The molecule is extremely greasy. It leaves the blood into fatty tissue quickly and returns from it over days, which is why tests stay positive long after the effects have gone.

    Measured in people. Written by a person from the study named beside the step. Not signed off as a reviewed claim.

    The measurement behind this step

    Very high lipophilicity and 95 to 99% plasma protein binding. Rapid distribution into adipose tissue with slow redistribution; terminal elimination half-life in frequent users is measured in days. THC-COOH, the inactive carboxy metabolite, is the analyte urine screens detect.

  4. What it acts on

    Partially activates CB1 receptors everywhere at once

    It docks into a receptor that normally responds to the body's own short-lived signalling molecules — but it arrives across the whole brain and stays for hours.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Partial agonism at CB1, a Gi/o-coupled receptor located presynaptically throughout cortex, hippocampus, basal ganglia, cerebellum and hypothalamus. Endogenous ligands anandamide and 2-arachidonoylglycerol are synthesised on demand and hydrolysed within seconds; THC is neither localised nor rapidly cleared.

  5. The change it makes

    Neurotransmitter release is turned down across many circuits

    The receptor's job is to tell the upstream nerve cell to release less. Doing that everywhere produces effects on memory, appetite, mood, coordination and time sense together.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    CB1 activation inhibits adenylyl cyclase and presynaptic calcium channels, suppressing release of glutamate, GABA, dopamine and other transmitters. Circuit-specific consequences follow from receptor density: hippocampal CB1 for short-term memory, basal ganglia and cerebellum for movement, hypothalamic and mesolimbic for appetite and reward.

  6. What that does for a person

    Symptom scores move a little; risk accrues with frequency and potency

    In trials of defined cannabinoids the effects on pain and spasticity are real and small. The documented harms — psychosis risk, dependence, hyperemesis — track how often and how strongly a person uses.

    Described, with no measurement named. No measurement is named for this step, so it is drawn as an unconfirmed link.

    The measurement behind this step

    Measured endpoints are 0-10 pain scales, the Ashworth spasticity scale and complete-response rates for chemotherapy-induced nausea. The psychosis association is dose-dependent by frequency and by THC concentration, with an adjusted odds ratio of 4.8 for daily high-potency use in EU-GEI. Tolerance to most effects develops with regular use, and a withdrawal syndrome with irritability, sleep disturbance and appetite change is recognised in DSM-5.

No suggested links are held for this record, so nothing is hidden from this path.

What we know
The record describes 5 steps from taking it to an effect in a person.
How we know it
Each step names the study behind it in the technical detail beside it.
What this does not prove
A change inside the body is a reason to look. It is not a result in a person.
Why it matters
A reader can see exactly where the chain stops being measured in people.
What we still do not know
No reviewed claim binds any of these steps to a named population.

What it would be like to takeRead from sources, not yet reviewed

Felt, measured, or meaningful

Three different things that get called the same word. Registered studies measured all three, and mixing them is how a blood test becomes a health claim.

Felt

Things a person could notice without a test.

  • neuropsychiatric inventory
  • tinnitus handicap inventory
  • numerical pain intensity
  • pain numeric rating scale
  • pain threshold
  • on the drug effects questionnaire
  • scores on the marijuana craving questionnaire short form
  • scores on the modified cigarette evaluation questionnaire
  • fatigue severity scale
  • becks depression inventory

and 3 more.

Measured

Things only a test, a scale or a device shows.

  • peak thc concentration
  • peak nicotine concentration
  • heart rate
  • leg strength

Meaningful

Things that change how a life goes, not only a number.

  • marijuana relapse
  • 25 foot walk test

A registered study says what someone planned to measure. It does not say what they found. A number moving is not the same as a life going better. The two are shown apart here.

Felt, but not shown to help. A person notices a change. No study showed it leads anywhere good.

Measured, but not felt. A number moves. The person notices nothing. Both can be true.

Measured, but not shown to matter. A number moves in the good direction. Nobody showed that lives went better.

Matters, but takes years. The result that counts may take longer than anyone would keep watching.

Names that fit none of the three (21)
  • behavioral measures
  • week 0 to week 3 in the rate of torque increase flexion
  • week 0 to week 3 in the rate of torque increase extension
  • week 0 to week 7 in the rate of torque increase flexion

  • 9 hole peg test
  • paced auditory serial addition test
  • incidence of treatment emergent adverse events
  • cue reactivity

These are harms, study-process measures, or names the rules did not recognise. They are shown rather than dropped.

What is missing or unclearRead from sources, not yet reviewed

Were people like you studied?

RNAWiki cannot tell whether a study fits you. It can show who was in it, and where the result stops carrying.

Who was studied

People similar to this profile were included.

  • In the United States, adults under state medical or adult-use programmes; a smaller number under research authorisations. Across Europe, patients under national medical-cannabis schemes using standardised, analysed plant material rather than an unregulated supply.

Who is missing from the studies

  • Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

Where the result stopped carrying

  • Cannabinoid hyperemesis syndrome was doubted for years because an antiemetic causing intractable vomiting looked implausible, until independent case series accumulated
  • Only 4 of the 79 trials in the largest systematic review were judged at low risk of bias, which is the real state of this evidence base
  • This is a scope explorer, not a diagnosis engine.
  • It shows who was studied so you can see whether people similar to you were included.

What it would be like to takeRead from sources, not yet reviewed

Why it might seem to do nothing

A real effect and a noticed effect are different things. These are the recorded reasons the two come apart.

It was studied for a different goal

The studies measured something else entirely.

On this record: Some registered studies measured things that match no goal on this page.

It was studied in different people

The people in the studies were not much like the reader.

On this record: Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

The evidence may simply be wrong

Small early studies often do not hold up.

On this record: RNAWiki has not yet published a reviewed conclusion for this use.

Other reasons RNAWiki checked and found nothing for (10)
A different form was studied
The studied form is not the form on the shelf. Nothing in this record points to this reason.
There was nothing to correct
Where a level is already normal, topping it up may change nothing. Nothing in this record points to this reason.
Something else had to happen too
In the studies it was paired with training, a diet or another treatment. Nothing in this record points to this reason.
The change is too small to feel
A real change can still sit below what a person notices. Nothing in this record points to this reason.
Day-to-day swing hides it
Sleep, food, stress and time of day move most numbers more than this would. Nothing in this record points to this reason.
Not enough time yet
The studies ran longer than the person has waited. Nothing in this record points to this reason.
It was not taken as studied
Missed days change the result, and studies count them. Nothing in this record points to this reason.
Something else changed at the same time
Two changes at once cannot be told apart afterwards. Nothing in this record points to this reason.
The product may not be what it says
Contents of a sold product are not always what the label states. Nothing in this record points to this reason.
No recorded reason
RNAWiki has nothing stored that would explain it. Nothing in this record points to this reason.

None of these is a reason to take more. Taking more is not a step this page ever suggests.

Worth asking a clinician aboutWritten into the record from the studies named on this page

Acute effects include tachycardia, conjunctival injection, impaired short-term memory, impaired coordination and reaction time, and anxiety or panic, which is dose-related and commoner in inexperienced users. Acute psychotic symptoms can occur at high THC exposure. With regular use: a DSM-5 cannabis use disorder with a recognised withdrawal syndrome, cannabinoid hyperemesis syndrome in a minority of chronic heavy users, and the dose-dependent association with psychotic disorder measured in EU-GEI. Smoking delivers combustion products; the respiratory evidence is confounded by concurrent tobacco use in most cohorts. Cannabis is not associated with fatal overdose through respiratory depression, because CB1 receptors are sparse in the brainstem respiratory centres.

Nobody counted how many people took this and were fine, so this cannot be turned into a rate.

Where this came from

Over a long time. No completed tested study window is recorded, so long-term effects are not established by the registry record.

Groups the studies covered thinly. Which groups were under-represented in the studies has not been recorded for this substance. Pregnancy, breastfeeding, children, older adults, and people with liver or kidney conditions are commonly excluded from trials; nothing here says whether they were.

What you could measure

This one is decided with a clinician, so this section holds questions to ask rather than a plan to run.

A single-person plan is offered only as a structure for observing yourself. It never calculates an amount to take, and it cannot prove cause.

Questions worth asking

  • Which of the trials of Cannabis Sativa SUBSP. Indica Top studied people like me?
  • What was measured, and for how long?
  • Was the result a laboratory value or a health outcome?
  • What would we watch for, and when would we stop?

Tracking can show whether something changed for you. It cannot show what caused it.

79 randomised trials: moderate-quality evidence in pain and spasticity, and small effects
In plain words
A JAMA review pooled 79 trials in 6,462 people. Cannabinoids beat placebo for chemotherapy nausea and moved pain and spasticity scores a little. Only four of the 79 trials were judged at low risk of bias.
What was measured
Pooled odds ratios and weighted mean differences for pain, spasticity and nausea across 79 randomised trials
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Whiting et al. searched 28 databases to April 2015 and included 79 randomised trials, 6,462 participants; 4 were judged at low risk of bias. Complete nausea and vomiting response was 47% versus 20% (OR 3.82, 95% CI 1.55 to 9.42, 3 trials). Pain response was 37% versus 31% (OR 1.41, 95% CI 0.99 to 2.00, 8 trials) with a weighted mean difference of -0.46 points on a 0-10 numerical rating scale (95% CI -0.80 to -0.11, 6 trials). Ashworth spasticity fell by a weighted mean of -0.36 (95% CI -0.69 to -0.05, 7 trials). The authors graded evidence as moderate quality for chronic pain and spasticity and low quality for nausea and vomiting, HIV weight gain, sleep and Tourette syndrome, and recorded an increased risk of short-term adverse events including serious ones. Almost all the included trials used defined cannabinoid products, not smoked plant material.

EU-GEI: daily use of high-potency cannabis carried nearly five times the odds of psychosis
In plain words
Across eleven European sites, people with a first episode of psychosis were far more likely to be daily users of high-strength cannabis. Where high-strength cannabis was common, first-episode rates were higher.
What was measured
Adjusted odds ratio for first-episode psychotic disorder by frequency and potency of cannabis use
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Multicentre case-control study, 901 patients aged 18 to 64 with first-episode psychosis and 1,237 population controls across 11 sites in Europe and Brazil, May 2010 to April 2015. Types of cannabis were classified by expected THC concentration into low potency (<10%) and high potency (>=10%). Daily use carried an adjusted odds ratio of 3.2 (95% CI 2.2 to 4.1) versus never use, rising to 4.8 (2.5 to 6.3) for daily use of high-potency types. Assuming causality, the population attributable fraction for high-potency cannabis was 12.2% (3.0 to 16.1) across all sites, 30.3% (15.2 to 40.0) in London and 50.3% (27.4 to 66.0) in Amsterdam. Site-level incidence correlated with prevalence of high-potency use (r=0.7, p=0.0286) and of daily use (r=0.8, p=0.0109). The design is case-control: it measures association and cannot exclude reverse causation or shared liability, and the authors state the causal assumption explicitly when reporting the attributable fractions.

The trials studied cannabinoids; the dispensary sells a plant
In plain words
The evidence base for medical cannabis is almost entirely built on defined drugs with known doses. Smoked flower of unknown potency is not the thing that was tested.
What was measured
That trial results obtained with dronabinol, nabiximols and purified cannabinoids transfer to inhaled plant material of unstated composition
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Of the 79 trials in the JAMA review, the interventions were overwhelmingly nabiximols, dronabinol, nabilone, purified cannabidiol and defined extracts — products with a stated milligram content and a fixed cannabinoid ratio. Whole-plant material is variable by cultivar, harvest, storage and preparation; the delivered dose from inhalation additionally depends on the person's inhalation pattern. The result is that a systematic review of "cannabinoids for medical use" cannot be read as a review of cannabis as consumed, and the direction of the discrepancy is not knowable in advance: the plant could be more effective than the isolate through additive constituents, or less, and no adequately powered trial of standardised whole-plant material against placebo exists for the main indications.

Cannabinoid hyperemesis syndrome: described in 2004, initially disbelieved
In plain words
Heavy long-term users can develop cycles of severe vomiting that stop when they stop using and come back when they restart. Hot showers relieve it, which is how the syndrome was first spotted.
What was measured
Symptom resolution on cessation and recurrence on rechallenge in a chronic-user case series
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Allen et al. described a series of chronic cannabis users in South Australia presenting with cyclical vomiting, in whom symptoms resolved on cessation and recurred on rechallenge, and who used compulsive hot bathing for relief. The paradox — an antiemetic drug causing intractable vomiting — meant the syndrome was doubted for years before independent case series accumulated. It is now a recognised presentation in emergency medicine. Frequency is not established; the syndrome is defined by the temporal relationship to use and by resolution on abstinence, which is also the only reliable treatment.

Federal rescheduling has been formally under way since May 2024 and is not finished
In plain words
The Justice Department proposed moving cannabis from Schedule I to Schedule III in 2024. The hearing was cancelled, restarted, and began again in June 2026. Meanwhile FDA-approved drug products containing marijuana were moved to Schedule III by a separate final rule.
What was measured
Status of the marijuana rescheduling rulemaking as of this audit
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
A notice of proposed rulemaking published 21 May 2024 proposed transferring marijuana from Schedule I to Schedule III of the Controlled Substances Act. DEA published a notice of hearing on 29 August 2024. On 28 April 2026 DEA withdrew that notice and terminated the pending hearing proceedings (91 FR 22778), and in the same issue published a new notice of hearing with proceedings beginning 29 June 2026 (91 FR 22777), citing Executive Order 14370. Separately and on the same date, a final rule (91 FR 22714) placed FDA-approved drug products containing marijuana in Schedule III, an action taken to satisfy United States obligations under the Single Convention on Narcotic Drugs. The botanical itself remains in Schedule I while the rulemaking is open. Schedule III would not make cannabis a prescribable medicine: it would remove the Schedule I research barriers and the section 280E tax treatment, and leave FDA approval as a separate requirement no plant preparation has met.

Blood THC is not a blood alcohol concentration, and per-se limits assume it is
In plain words
THC hides in body fat and leaks back out for days. In a frequent user, a blood level says how much has accumulated, not how impaired they are right now.
What was measured
That a whole-blood delta-9-THC concentration indexes current impairment the way a blood alcohol concentration does
Effect estimate
No reviewed effect estimate exists for this record.
Limits
See the technical detail.
From the source
Delta-9-THC is highly lipophilic and distributes into adipose tissue, from which it redistributes over days to weeks in frequent users. Blood concentration therefore falls rapidly after inhalation while impairment persists, and remains detectable in frequent users long after impairment has resolved — the two curves diverge in opposite directions in different populations. The consequence is that a per-se blood threshold of the kind used for alcohol has a much weaker relationship to functional impairment, and this is a measurement fact about the analyte, not a policy opinion. The analytical measurement is reliable; the inference drawn from it is the problem.

The older medicine-wide conclusion held in this record

Written for a clinical reader, and about the medicine as a whole rather than about one indication, population and set of trials. RNAWiki does not treat it as a programme conclusion and no reviewer has signed it off in that form. It is here word for word because it is what the record holds.

A plant whose principal active molecule is well characterised and whose preparations are not, with moderate-quality trial evidence for cannabinoids in pain and spasticity, a replicated dose-dependent association with psychotic disorder, and a federal schedule that has been under formal review since 2024.
