No, it's stronger.
"We've seen a big increase in marijuana potency compared to where it was 20 or 30 years ago," lab founder and director of research Andy LaFrate, Ph.D., said in a video released by ACS. Based on testing in laboratory equipment, "I would say the average potency of marijuana has probably increased by a factor of at least three. We're looking at average potencies right now of around 20 percent THC."
THC, or tetrahydrocannabinol, is the psychoactive compound in marijuana that acts on the brain to produce the feeling of being high.
"As far as potency goes, it's been surprising how strong a lot of the marijuana is," LaFrate said of the samples his lab has tested in recent months. "We've seen potency values close to 30 percent THC, which is huge."
Compared to the 1980s, when federal officials say the level was about 4 percent, "that's a dramatic increase in the part that gets you high," CBS News medical contributor Dr. David Agus said on "CBS This Morning."
