Care to speculate on what the "occasional" pot smoker has stored in his lungs and done to his brain ? (i.e. changes in the activity of nerve cells containing dopamine , etc) "
No need to speculate; the "occasional" pot smoker doesn't develop lung cancer (or any significant pulmonary disease). Now that I've settled that matter, I can't unfortunately, begin to speculate on the relative CNS effects of a six-pack versus a joint. Believe the "expert opinion" of your choice for that.
Sorry Doc, but I'll take a bottle of Mosel Auslese or a six pack of German beer over a joint every day of the week.
Maybe a six pack everyday might be a little much. That's the equivalent of a case of Coors Light or Budweiser. Since I've been hitting the gym 4-5 days a week, I think I could handle a liter a day without deleterious effects.
