You NEED tobacco to smoke. You NEED alcohol to get drunk. You don't NEED condoms to have sex.

You don't need to buy tabacco to smoke either.
Not hard to grow your own.
You don't need to buy alcohol to drink.
Not that hard to make beer or wine in your basement or garage. It's called moonshine in some areas.
I also agree you don't need a condom to have sex, but you need one if you want to think you are having "safe" sex.
Of course you could put higher taxes on birth control pills, spermacides, etc.
