Lots of harm by alcohol actually. It's been proven to kill your brain cells, make you more aggressive, it contains lots of calories and carbs which for a 40 year old dude ain't the best thing for you, and it, like marijuana, is highly addictive. Except drugs make you look old and horrible and dependant on that ****. Whiskey is good though.I've never smoked pot so I wouldnt know what its like. But I know how alcohol affects me....it makes me hyper then it makes me sleepy. No real harm in my opinion. No harm in my particular case I should say. I know that alcohol makes a lot of people angry and violent which is very very scary!
