Pot is becoming more potent, a new study suggests.
In the study, the researchers looked at more than 38,600 samples of illegal marijuana seized by the U.S. Drug Enforcement Administration over 20 years. They found that the level of THC, or tetrahydrocannabinol— marijuana's main psychoactive ingredient — in the marijuana samples rose from about 4 percent in 1995 to about 12 percent in 2014.
Conversely, the level of CBD, or cannabidiol — an ingredient sometimes touted for its potential health benefits — fell from about 0.28 percent in 2001 to less than 0.15 percent in 2014.
But smoking marijuana with high doses of THC may involve a higher risk of negative health effects, such as psychosis orpanic attacks, he said.
