What a ridiculous strawman you’re setting up. Why are you ignoring the already established historical record of successful pot smokers— like Feynman and Sagan?

But suggest that his mental illness might have been exacerbated by pot use, and that’s off limits.

His mental illness was probably exacerbated by pot use. I said so in my response to Frum’s article. I have no idea how you missed it, except that you’re not actually interested in having an honest argument.

Frum’s argument is based on two ideas:

1. That it’s possible to make pot difficult to acquire.

It’s not. Prohibition has shown us this; when a substance has wide cultural acceptance, it’s not going to be able to be suppressed.

2. That already-existing mental illnesses being exacerbated by marijuana is an argument against the use of marijuana in general.

Obviously, it’s not. It’s an argument against the use of marijuana if you have a mental illness.

Do you understand?
