CNN —Users of marijuana had statistically higher levels of lead and cadmium in their blood and urine than people who do not use weed, a new study found. Marijuana users also had 22% higher cadmium levels in their blood than non-users, and 18% higher levels in their urine, Sanchez said. “Our study wasn’t able to tease apart whether or not self-reported cannabis users were using medical or recreational cannabis, so we can’t say definitively if medical cannabis users specifically had higher metal levels,” she said. Heavy metals aren’t just in marijuana — tobacco smokers are exposed to even more types of toxins. While that’s good news for the environment, it’s worrisome for marijuana users.
