Marijuana is a plant that contains molecules including CBD and THC (9-tetrahydrocannabinol). These molecules are responsible for the “high” that marijuana produces as well as other effects.
People who smoke cannabis regularly or take it by vaping or other methods are likely to build a tolerance to the drug.
Cannabis consumption is legal in many states, but that does not mean that marijuana use is safe.
People who use marijuana heavily and build a tolerance often suffer mental health effects and impairments in certain functioning.
How Long It Takes To Build A Marijuana Tolerance
Studies have shown that weed tolerance can increase in just two to four weeks when using the drug daily.
The development of a drug tolerance to the psychoactive effects is mostly due to THC tolerance, because THC is the molecule that is responsible for most of cannabis psychoactive properties.
People who develop a tolerance to marijuana may try to take concentrates such as “dabs” or edibles containing a lot of THC in order to feel the drug’s effects as intensely as they used to.

Factors That Influence Cannabis Tolerance
Everyone’s tolerance for marijuana is different. The same amount of weed will not give the same effects to two different people.
Factors that influence cannabis tolerance include:
- Cannabinoid receptors: CB1 receptors are located throughout the body and are responsible for processing cannabis. Everyone’s cannabinoid system is different, leading to different tolerances.
- Frequency of use: The more someone uses marijuana, the more their tolerance to the drug will increase.
- Age, weight, body chemistry: Different people have different natural tolerances to cannabis. In general, heavier people will have a higher tolerance and elderly people will have a lower tolerance.
Is A Marijuana Tolerance Reversible?
Many people who develop a cannabis tolerance find that they cannot get the same effect by smoking weed as they used to.
This is why tolerance breaks or “t-breaks” are common among cannabis smokers. Tolerance breaks are when someone stops using weed for a short period so that their tolerance begins to increase again.
Marijuana tolerance is reversible, although after heavy use, tolerance may never decrease back to the same level as when someone used the drug for the first time.
How Marijuana Tolerance Can Affect Withdrawal Symptoms
People who use cannabis every day or most days will develop a tolerance to the drug, and their body will get used to operating with cannabis in the system.
Although marijuana does not lead to chemical dependence in the same way that other drugs like cocaine or heroin do, withdrawal symptoms can still happen.
Marijuana withdrawal symptoms may include:
- decreased appetite
- mood changes
- cravings for marijuana
- stomach issues
