Which is worse out of cigarettes or marijuana?!

Worse in what way?

I would say cigarettes overall. They are more physically addicting, more expensive over time, taste bad, smell bad, cause more that just lung problems and the high doesn't last as long ;D.

I know this is a little off topic but I recommend trying everything one time(except hard drugs like coke, heroin & meth). Don't wait until your the only one in school who hasn't tried weed or drank before. I knew kids like that in high school who were SO against any kind of drugs or drinking, but once they got to college they weren't ready to party with the others who had been drinking and smoking all throughout high school. They would always be the ones to look like a total fool because they didn't know how much was too much. One of my friends died this way. He was a straight A student until he got to college. Moderation is key and Maturity is knowing when enough is enough.

personal experience

assuming the marijuana isn't laced with another drug, marijuana would be much safer. It also depends how you use either of these substances. If you compare using snus to smoking marijuana out of a can, then tobacco might be healthier. But if we compare the healthiest form of each (for tobacco, use snus;for marijuana, use a vaporizer or put it into cooked foods) then marijuana is healthier. Tobacco has been proven to cause many types of cancer, whereas marijuana has only caused one type in females and 2 in males (one is testicular cancer, i forget the other).

common knowledge, research, and forgotten, but reputable internet sites

It's easy to quit smoking marijuana but I can't break the habit of tobacco. I quit smoking and ended up dipping to save my lungs but I still smoke pot all the time. Hell, one of my friends is an engineer and smokes more than most people I know. If you never smoked before then don't judge a book by it's cover. It's not nearly as harmful and bad as people make it out to be.

Cigarettes for sure. They're the most addicting thing I've ever tried. It's the only thing I regret in life, starting smoking. Marijuana is non addictive. That's been proven. I've done a lot of stupid **** but cigarettes were the worst. Worse than smoking crack.

cigs..everyone knows that!
even on the side of the box it says that it causes lung cancer..goto a marijuana store and it doesnt say anything..also it doesnt kill brain cells..it has NEVER been proven too...just propaganda!

marijuana.
Because not only do ur lungs clog up, but u lose brain cells that never come back. There both addicting.
