I did not, and am not, saying that it&#x27;s harmless. That would be ridiculous.<p>But if it&#x27;s less harmful than alcohol, a substance which is legal for consumption and moderated by the government, why should it be illegal? What&#x27;s your justification for saying marijuana should be banned for reasons of harm, when you can&#x27;t establish that it&#x27;s more harmful than more easily available alternatives?<p>Or are you also arguing that alcohol should be banned, as well?<p>Edit: To answer your initial question, the logic here is &quot;One harmful substance is legal, thus other substances which are less harmful should probably also be legal&quot;.
