Is weed really bad for you?

No as long as you don't get busted or have to take a pee test and lose your job. Other than that I see no problem. Oh yeah it's exspensive.

Yes and no.  Disregarding the legality of it (of which I'm sure you're aware), pot can slow reflexes as in driving a car or other places where your attention is required, as pot can slow your reflexes much as alcohol does.  If you're not driving or other activities, and are in your own home or somewhere else you're stable, then it's probably OK (except for its legal issues).  However, it's considered a "gateway drug", in that if you know where to get it, it's probably from a dealer of some kind.  Since dealers deal in other drugs other than pot, they might get you to try something else which will make you "feel better" or "higher", usually free the first time.  If you try it, and like it, you'll want more, which the dealer will be glad to sell you.  As you like it more and more, the dealer will get you to try stronger and stronger drugs, most of which are addictive.  Before long, you ARE addicted, and HAVE to have the drug; that's how addicts get started. 

So, as long as you are limiting yourself strictly to pot, and resist dealers or other people trying to get you to use something "better", and you are not driving, etc., then it's safer than alcohol  (you can't overdose on pot; you can on alcohol), However, it's more dangerous than tobacco, and can probably cause cancer of the lungs and other organs (this is unproven, but, in my opinion, probably true).

No. Actually marijuana is less harmful to your body than tobacco and alcohol unless it takes over your life.

THC is not an addictive substance but, just like when you first have sex, it can become psychologically addictive since you enjoy this "high" feeling so much, there's a point where you can't get enough of it unless you put your mind on something else and it brings consequences.

I'll give you an example that will make my point clearer.

On one hand we have John. He has a good job, a beautiful girlfriend, he goes to college and is almost done with his second career. John smokes marijuana once a week to relax.

On the other hand we have Mike. He smokes marijuana with John.

While John can handle his "drug addiction" because he lives a very active life, Mike is developing a shell on his persona that's preventing him from advancing in life because he's staying in an "all-time high" state. That's not any better than being drunk all the time.

I recommend smoking weed only if you have your life sorted out. Too much of something is good for nothing.

I hope my answer was helpful to you. Peace.
