Simple analogy: If a person were to kill himself for the sake of entertaining the crowd, this act would still be considered illegal by the government and efforts to hinder and discourage it would be created.  An appropriate example is the one of dangers of alcohol and tobacco, which were not known until after they had become normalized in society. Once the dangers were known, the public were so used to it, that they wouldn’t condone a ban by the State. If alcohol were introduced tomorrow it would be banned, as shown by the attitude towards narcotics and steroid use has shown. Governments have tried to reduce sales by having high levels of tax on tobacco and alcohol anyway. Moreover many states are restricting choice in tobacco and alcohol by introducing limited bans, such as on smoking in public places. The proposition cannot use the fact that tobacco and alcohol are legal as a defense of the use of drugs. This should be seen as an equally detrimental act and thus illegal.
