But an adult is and should be allowed to develop a nicotine addiction. The reason why people do above all else is that nicotine is an intoxicant and (to most people) pretty pleasant. It's a rational choice.

Don't let them sell to kids. Include scary images on the box. Whatever you do, the truth is that human beings like their drugs and this one isn't really that bad.

Should an adult be allowed to develop a heroin addiction? Why or why not?
