If you find that you need to consume more cannabis than usual to experience its effects, it might just be a weak strain, but it's probably because you've grown tolerant. However, science is showing us how quickly our tolerance level lowers so that we can feel the effects of cannabis more intensely again. The results of a study published in the January 2016 issue of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging (led by Deepak Cyril D’Souza, Professor of Psychiatry at Yale School of Medicine) explain how consumers with high tolerances to cannabis only have to wait a few days to begin to see their tolerance levels return to normal. To help you along, we've listed a few ways you can “fix” your cannabis tolerance, but if you're consuming marijuana regularly for medicinal purposes, consult with your doctor before changing your routine.

1. Switch to cannabidiol (CBD) oil
Consuming CBD oil that doesn't have tetrahydrocannabinol (THC) – the cannabinoid that causes the cerebral “high” pot is so famous for – delivers a therapeutic, non-psychoactive cannabinoid to your system while giving the receptors that THC targets a chance to recuperate.

2. Microdosing
Consuming smaller amounts of cannabis (rolling smaller joints, packing smaller bowls, using a one-hitter, etc.) or curtailing your usage to once a day will help bring your tolerance level back down to normal.

3. Switch Your Method
Making a change to how you consume cannabis may help normalize your tolerance levels because you may not need as much to feel the effects. Consider concentrates, edibles, or tinctures if you've been a long-time smoker, or try vaporizing some fresh flowers if you haven't inhaled cannabis in a while.

4. Switch Your Strain
Even your favorite strain will lose its effectiveness after a while if the cannabinoids it produces are the only ones you're exposed to; the good news is, however, that after a few weeks away from your go-to, you'll get to rediscover those desired effects.

5. Abstaining
The aforementioned study confirms that abstaining from cannabis is the only way to really “fix” your marijuana tolerance level, with results showing that our bodies need only two days of cannabis abstinence before showing signs of a lowered tolerance level and that by 28 days of abstinence that tolerance is practically non-existent.
