Technicly .........cigarettes are much worse than puffying mary jane.
Tabacoo has been shown to cause canser, birth defects, many brething ailments, and heart problems.
Marijuana on the other hand can cause loss of motery function on a less sever amount than achohol but loss of control non the less.
Its not been shown to cause canser or birth defects breathing problems is sceptpical since most people who turned up with those also smoked tobacco.
As for heart problems there is evedence to support that but thats because of the toll it takes on your metobolic system.
But is it a sin?
No I dont think so after all some of the food we eat is just as bad for us as those things.
Just think of McDonalds as a 99 cent heart attack meal.
Would be scary to think everyone was sining that much.
But while I dont think it is a sin .
I DO think its very stupid.
Thats the grown up half of me speaking
I quite smokeing both of those things nearly 6 years ago and I gotta say I'm happy I did!
