Factors that Determine Marijuana’s Potency and Effects
Smoking produces intoxication quickly, within minutes, and its effects are fairly predictable from one time to another.Eating marijuana-infused food causes the THC to be absorbed more slowly, with intoxication beginning between 30 minutes to 2 hours after ingestion, and the effects can be difficult for the user to predict.
The precise effects an individual will experience depend on how much marijuana is consumed, how potent it is, how it is ingested.
Dried marijuana is most often smoked, but can also be used to infuse various foods and eaten. THC-rich marijuana extracts are also increasing in popularity, including hash oil and a hard, brittle preparation called “shatter.” Such extracts are particularly dangerous because extremely large amounts of THC can be ingested by users very quickly.
Marijuana contains more than 60 related psychoactive chemicals, called cannabinoids; however, the most abundant of these is delta-9-tetrahydrocannabinol (THC). The amount of THC ingested when using marijuana determines the intensity of the high, and the potency of different strains of marijuana is a result of the level of THC they contain—varying from 3% to 20%, on average.
