From experience...
My brother and his group of friends all lift almost regularly, and a few are pretty jacked, but they all smoke weed. My bro at least 1 blunt a day, and he lifts between 2-4 times per week. BTW he's been smoking for a few years and lifting about 5 months. So I'm not sure how much weed effects your lifting, but he definitaley can't run for **** (though he used to be extremely fast). He drinks maybe once a week or so, so that isn't a major factor.
So I don't recommend trying to smoke and drink while working out, but if you are, in my brother and his friends' case, weed doesn't really effect their muscle growth, but they can't do anything endurance wise.
