And yes, it's illegal to make liquor in bathtubs, but it's not illegal to brew beer at your house, which is another inconsistency in the law. Of course, why would you want the state involved in any of this. If you are a conservative as you claim to be, wouldn't it make more sense to scale back state interventionism completely and let market competition push out shoddy products?
The opposite of market competition is either nationalization or prohibition. I highly doubt you favor nationalization of drug production. Do you remember how prohibition went? (Badly) And yet you want to continue marijuana prohibition and add to that other drugs.
No, it does make you a hypocrite to say that you believe the government should let us lead our own lives, and then calling for certain nonviolent activities to be banned. In reality, what you're saying is, the government should let us lead our lives as long as they all conform to my idea of what is good, otherwise the state should step it. If you truly respect personal liberty, you must respect the liberty of others, however much you may disagree with their individual choices. So long as the activity does not infringe on someone else's life or property, there is no justification for state action. It's not enough to say something is dangerous or pointless and that you hate it, and therefore it should be banned. I hate lots of things, but that is certainly not grounds for banning them.
Finally, I don't appreciate your implications about me and my beliefs. For one, I have never smoked marijuana, nor do I plan on it. Secondly, why would you think that, given my shpiel on individual liberty, I would want a law passed that suppressed people's opinions (as if that were even possible)? You are free to give your opinion and I am free to critique it.
