The fact that weed is illegal right now is almost laughable.

Not too many people seem to have an issue with legalized alcohol and tobacco.

Weed, on the other hand? That's a different story. Roughly half of America still gives legalized marijuana a thumbs-down.

But as we know, public opinion doesn't necessarily take facts into account.

Research shows that while drinking alcohol can be dangerous and smoking tobacco can harm your lungs, marijuana is relatively safe to use.

In this video by Healthcare Triage, Dr. Aaron Carroll points to a study published in the Journal of the American Medical Association that found using tobacco had pretty awful effects on a person's lungs — and that marijuana use had none.

At the same time that study was published, a different study by the Centers for Disease Control and Prevention found excessive drinking causes roughly 80,000 deaths per year.

So, if we do the math...

Although Carroll points out the pro-pot perspective, he makes sure to note marijuana should be regulated like tobacco and alcohol and legal only for people above a certain age.

"There are lots of things that are dangerous but regulated," Carroll says, noting that smoking marijuana can affect short-term memory and lower reaction time, among other things.

"We don't let kids buy tobacco or alcohol, [which] totally makes sense. The same should apply to marijuana."
