The Cannabis Microdosing Schedule (Fadiman Protocol Adapted)
Overview
The Fadiman protocol — originally developed by Dr. James Fadiman for psychedelic microdosing — has been adapted by cannabis users as an effective scheduling framework. The core pattern is simple: dose on Day 1, rest on Days 2 and 3, then dose again on Day 4. This three-day cycle prevents tolerance buildup, allows you to compare how you feel on dose days versus rest days, and gives your endocannabinoid system time to recalibrate between doses. For cannabis specifically, this schedule works exceptionally well because cannabinoid tolerance develops faster than with classical psychedelics. The adapted cannabis version of the Fadiman protocol typically runs in 4-week cycles. During the first week, you establish your baseline dose (usually 1-2.5 mg THC). Weeks 2-3 are the core protocol period where you follow the dose-rest-rest pattern and track your responses. Week 4 is a full rest week with no dosing, allowing complete tolerance reset and self-assessment. This cyclical approach ensures that microdosing remains effective long-term and prevents the gradual dose creep that leads many cannabis users into higher consumption patterns.
Protocol
Week 1 (Baseline): Take your chosen dose at the same time each day for 5 consecutive days. This establishes how the dose affects you consistently. Track mood, energy, focus, and sleep quality daily. Weeks 2-3 (Fadiman Cycle): Follow the dose-rest-rest pattern. Dose on Day 1, observe and record on Days 2-3 without dosing. Note any residual effects or afterglow on Day 2. Day 3 should feel like your natural baseline. Dose again on Day 4 and repeat. Week 4 (Integration Rest): No dosing for the entire week. Compare your baseline mood and function to pre-protocol levels. Assess whether the protocol is providing meaningful benefits. Adjust dose up or down by 0.5-1 mg for the next cycle if needed.
Dosage Range
Your established minimum effective dose (typically 1-5 mg THC)
Schedule
Dose on Day 1, rest on Days 2-3, repeat. Full week off every 4th week. Dose at a consistent time (morning recommended) on dose days.
Expected Effects
- •Sustained benefits without tolerance buildup
- •Clear comparison between dose days and rest days
- •Residual positive effects often noticed on Day 2 (afterglow)
- •Day 3 returns to natural baseline for honest self-assessment
- •Monthly reset week prevents long-term tolerance development
Tips for Success
- •Use a simple calendar or habit-tracking app to mark dose and rest days
- •Rate your mood, focus, and energy 1-10 every evening — regardless of whether you dosed
- •Pay attention to Day 2 (rest day after dose) — many people feel the best on this day
- •If you feel no difference between dose and rest days, your dose may be too low
- •Do not skip the Week 4 rest — it is essential for long-term effectiveness
Important Warnings
- ⚠If you find it difficult to take rest days, this may indicate psychological dependence
- ⚠The protocol requires honest self-assessment — consider enlisting a trusted friend for outside perspective
- ⚠Adjust the schedule if you have obligations that preclude even slight cognitive effects on dose days
- ⚠This schedule is a guideline — some people do better with every-other-day dosing instead
Frequently Asked Questions
Why can't I just microdose every day?
Daily microdosing accelerates tolerance buildup, meaning you will need progressively higher doses for the same effect. Rest days allow your CB1 receptors to resensitize. The Fadiman schedule also provides built-in comparison days so you can objectively assess whether microdosing is actually helping versus placebo effect.
Can I adjust the schedule if dose-rest-rest does not work for me?
Absolutely. The Fadiman protocol is a starting framework, not a rigid rule. Some people prefer every-other-day dosing (dose-rest-dose-rest). Others dose 4-5 days per week with weekends off. For chronic pain or anxiety, daily dosing may be appropriate — just be mindful of tolerance and take periodic multi-day breaks.
What should I track on dose days versus rest days?
Track the same metrics every day regardless of dosing: mood (1-10), energy (1-10), focus (1-10), sleep quality (1-10), anxiety level (1-10), pain level (1-10 if applicable), and any notes about notable experiences. After 2-3 weeks, patterns will emerge showing the impact of your microdosing protocol.
How long should I follow the Fadiman protocol before assessing results?
Commit to at least one full 4-week cycle before making a judgment. The first week is calibration, weeks 2-3 are the actual protocol, and week 4 is integration. Many people notice meaningful patterns by the end of week 2, but a full cycle gives you enough data points for confident assessment.
