> Why would they be any different from tobacco consumers?

Marijuana attracts an earthy, naturalistic sort of crowd. I have no proof of this, but it's been my experience.

> Don't most of the factors that make tobacco different from the average business apply equally to cannabis?

The health risks of marijuana are much better understood now than the health risks of tobacco (more particularly cigarettes) were in the 1950s. There's simply less room to lie, for one thing, which was far and away the most atrocious thing that Big Tobacco did. And the mere fact that marijuana has been illegal for so long and developed its own culture underground makes it hard to compare.

> They seem to serve a similar social function. Indeed don't people frequently smoke a mix of the two?

In Europe it's common to mix the two, but for most Americans no. I usually smoked alone anyway, it's not a social thing at all for many. You're really comparing apples to oranges here. Marijuana and tobacco as different as LSD and beer in terms of their effects.
