Cannabis microdosing

Microdosing = so little THC or CBD that the effect is felt but no high sets in. Goal: focus, mood lift, pain relief — without daytime impairment.

THC microdose: 1–3 mg (below ~5 mg intoxication threshold). CBD micro usually unnecessary. Best route: sublingual oils or precise vape draws. Fadiman: 1 day dose, 2 days off. Evidence is thin — users report focus, less anxiety, better pain control. Not for CB1-sensitive people.

Why microdose?

Cooper 2013, Wallace 2015: small THC doses sometimes outperform larger ones. Biphasic curve.

Goal: hit the therapeutic corner without paying the price (high, tolerance).

Practical doses

THC sublingual: 1–2 mg every 4–6 h.

THC inhaled: one mini-puff of a 15 % flower via vape.

Protocols

Fadiman: day 1 dose, days 2 + 3 off.

5:2: five micro days, two off.

Who it works for

Good: chronic pain, mild anxiety, ADHD-like distractibility, migraine prophylaxis.

Not good: CB1-sensitive individuals, panic disorder, under-25s, psychosis family history.

FAQ

Micro vs placebo?

Hard to tell. 4-week journal with blinded placebo days helps.

Addictive?

Not physically at 1–2 mg. Psychologically possible.

Drug test?

Yes — even 1 mg is detectable for days.

Microdose at work?

THC is illegal in Switzerland regardless of dose. CBD is fine.
