Let's assume laws under legalization would make pot similar to alcohol (21 age limit, no driving under the influence, etc.)
This take is an answer to take Marijuana Should be Legalized by @michellebrown48 hence construction is similar to it.
1) It's extremely addictive for some people:
It would be malpractice to say that cannabis isn't addictive. Anybody who's experienced it, actually been addicted to it, knows how profound that addiction is... The difficult thing about marijuana addiction is some people, even though they're addicted can do fine with it for many many years before they start to have difficulty, but eventually the high starts wearing off, people start smoking a lot more to try to get that high back and that's when they descend into difficulties. ...I've been treating cannabis addiction for 20 years. When people are addicted to cannabis, cocaine, and alcohol the drug they have the most difficult time giving up is the cannabis. It is extremely addictive...for some people. I think that's where people get confused. It's not very addictive for many people. It's a small subset of people with a genetic potential for addiction. But for them, it is really tough. You only need to talk to them, they'll tell you how tough it is.

2) It Has No "Acceptable Medicinal Use"
Marijuana is not approved by the Food and Drug Administration (FDA) so its use is unregulated. The FDA, Substance Abuse and Mental Health Services Administration, and National Institute on Drug Abuse have found no sound scientific studies supporting medical use of crude marijuana. The FDA’s guidelines for a drug’s approval require that certain factors be established: dose quantity; frequency and duration of administration; and interaction with other medicines. None of these has been determined for marijuana. Never has smoking been an accepted method of administering any medicine. There's also an article posted by Washington Post explaining 5 reasons marijuana is not medicine
3) Marijuana is terrible for your mental health:
Marijuana may even be WORSE than cigarettes. At least cigarettes don't peel points off of your IQA ANorthwestern University study found that marijuana users have abnormal brain structure and poor memory and that chronic marijuana abuse may lead to brain changes resembling schizophrenia. The study also reported that the younger the person starts using marijuana, the worse the effects become.
4) It has Physical Consequences as Well
Physically, Marijuana is even more harmful than cigarette smoking. The immediate effects of taking marijuana include rapid heartbeat, disorientation, lack of physical coordination, often followed by depression or sleepiness. Some users suffer panic attacks or anxiety.
But the problem does not end there. According to scientific studies, the active ingredient in cannabis, THC, remains in the body for weeks or even months.
Marijuana smoke contains 50% to 70% more cancer-causing substances than tobacco smoke. One major research study reported that a single cannabis joint could cause as much damage to the lungs as up to five regular cigarettes smoked one after another. Long-time joint smokers often suffer from bronchitis, an inflammation of the respiratory tract.
Marijuana can change the structure of sperm cells, deforming them.
Thus even small amounts of marijuana can cause temporary sterility in men. Marijuana use can also disrupt a woman’s menstrual cycle.
5) Amsterdam's Failed Experiment.
Let's consider ideal conditions and arguments by legalization supporters true. Then legalization of it should work, right? Amsterdam is the most famous place across the world that has effectively legalized pot. It has even turned into a tourist destination for potheads. Legalizing weed has been a huge success there, right? Actually, not so much...Its citizens are now alarmed that their children are increasingly being exposed to it. Netherland is the first country to ban marijuana in schools.
Do you still think it should be legal? share your reasons!
