Pot-puffers, beware! Marijuana is a lot stronger than it used to be says a Denver-based testing firm who found that the THC (the ingredient that gets you high) from legal marijuana sold in Colorado is two to three times greater than what our parents used to smoke.

The increased potency may be too strong for Baby Boomers to handle, plus, medicinal pot users should avoid the recreational variety, as it does not contain cannabidiol (the nausea-subsiding compound). So before you light up that joint in the Rocky Mountain state, be sure to do your homework.
