This is true for come people but there are different reactions to the use of marijuana. For some people, they tend to get nervous because of the loss of control from marijuana. So this may not be necessarily true and a reason for marijuana to be legalized.
People believe that cigarettes are worse for your lungs than marijuana, but that isn't necessarily true. Yes cigarettes are very bad for the lungs but marijuana has double the amount of carcinogens than cigarettes. There are so many because with marijuana, people inhale it deeper than a cigarette. Knowing all the diseases a cigarette can cause just imagine the harm marijuana can cause with that many carcinogens. In conclusion, Marijuana should not be legal.
Marijuana should not be legal because it is extremely harmful to the important organs in the body. One is the brain. Marijuana can cause a bad memory along with a damaged brain. The brain is damaged because marijuana causes the blood vessels to be compressed/restricted causing blood not to get to the brain completely.
Marijuana should be legal because there would be more control and safety. Not only would it be safer according to crime, but it is a safer product. When marijuana is bought off the street, what could be in the drug is unknown. It could be laced with different drugs that could make it extremely dangerous. If it is legal, whats inside the marijuana will be controlled and known.
