Since weed is natural, it’s completely safe. It’s just a plant, right?

While smoking weed may not have the same risks as using synthetic drugs, it's not completely safe. Like cigarettes, smoking cannabis can damage your lungs.

If consumed by teens and those in their early 20s, cannabis can also affect brain development. (There is still a lot more to learn.) When weed is combined with other substances such as alcohol or tobacco, the health risks are higher.
