Cigarettes are actually more addictive than cannabis. You have some research to do. Cigarettes create a physical dependence, your body feels that it needs the nicotine, and there are consequences when it doesn't get the dose it needs. I could go on, but you know what these are already. However, THC activates the cannabinoid receptors in the brain, no such physical dependence happens. There is a psychological dependence, but this just means that you like it. There's a psychological dependence to sex, too.

Cigarettes and cannabis are two totally different things. Cigarettes are terrible and contain horrible chemicals. Cannabis just makes you feel funny for an hour.
