If necessary for the general betterment of society. That is the basis of all law. Someone's rights are always infringed upon to make society work.
No sport, that is what is needed for a civil society. Unabated individual rights devolves into anarchy and rule of who is strongest. Don't you understand that civil society requires a balance of competing rights; so in effect everyone's' absolute rights are infringed to make society work. It also takes a continuous adjustment of that balance as times and mores change.
From the Marijuana studies . . . Marijuana is far less harmful to human health than other banned drugs and is less dangerous than the highly addictive but perfectly legal substances known as alcohol, caffeine, and tobacco. Marijuana cannot lead to a fatal overdose. The myth that it leads users to more powerful drugs has long since been disproved. Casual use by adults poses little or no risk for healthy people. Its effects are mostly euphoric and mild. Marijuana isn’t addictive in the same sense as heroin, from which withdrawal is an agonizing, physical ordeal. Although few marijuana users develop dependence, some do. But they are less likely to do so than users of other drugs (including alcohol and nicotine) and marijuana dependence appears to be far less severe. When heavy users stop, some get short-term symptoms such as irritability, sleeping difficulties, and anxiety that are usually described as relatively mild. From 4 decades of personal experience . . . You don't trip or hallucinate on weed. You don't get a narcotic rush on weed. You don't have manic highs like speed, you don't get depressing lows like downers. You don't lose control of mind and body like alcohol. The main effect of weed is a feeling of contentment. That is why people smoke it. Marijuana has two negative factors. One is minor--the flip side of a feeling of contentment is that if you stay stoned every waking moment it leads to complacency. You can be content doing almost anything when high, including doing nothing at all. The other is major--you can go to jail. It really, really needs to be legalized. The only social problem involving marijuana is that it is a black market commodity. It requires smuggling and risk, which is expensive. The expense makes it involve a lot of money, which gets criminals involved in trafficking. Legalization would eliminate that.
I'm not so sure legalization would eliminate the black market totally. In Colorado legal weed is very expensive. If legal weed cost $450 an ounce and somebody can grow or smuggle weed and they can make a profit selling for $300 an ounce or less they will continue doing it.
