Is smoking weed as bad as smoking cigarettes?
Answer
Smoking tobacco stuffs up your body.
Smoking weed stuffs up your mind.
You decide. Answer
Marijuana is much safer to smoke than cigarettes because of many reasons. First of all, marijuana isn't physically addictive, as opposed to nicotine in cigarettes. Marijuana doesn't damage the brain, and moderate smoking of marijuana poses little threat to the lungs.
Some might say that marijuana is more potent these days than they were back in the 60-80's, making them quite dangerous, however it's the same marijuana they smoked back then so that's a myth.
People also smoke marijuana less often than cigarette's because they're not physically dependent on it, decreasing the chance of any problems with the lungs dramatically. Plus it also has some medicinal value, so that's another plus.
So, no, it's not as bad, not even close. Answer
Smoking marijuana, is (in my opinion) probably as dangerous as tobacco, in terms of smoking-related diseases. Most cigarettes today are typically filtered, while most people smoke marijuana without a filter, be it a joint, a blunt, a bong, or a bowl/pipe. Additionally, people tend to hold in marijuana smoke longer than they hold in tobacco smoke, because they want to get as high as possible.
However, people who smoke cigarettes typically smoke (on average) 1 pack, or 20 cigarettes, a day. Most pot-smokers do not smoke 20 joints a day. So, since you usually don't smoke anywhere near as much marijuana as you do cigarettes, the risk of smoking-related diseases decreases a lot.
Numerous studies also suggest that marijuana may cause a decrease in fertility, in both men and women.
