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.
