Tobacco itself does not appear to put holes in the brain, however, the main component of the drug, THC, may be involved in changing brain chemistry which can result in behavioâ¦ral effects. These effects are more evident the earlier exposure begins. The toxic effect of cigarettes is generally from additives.
These effects make you want to use tobacco and lead to dependence. At the same time, stopping tobacco use causes withdrawal symptoms, including irritability and anxiety. While it's the nicotine in tobacco that causes nicotine dependence, the toxic effects of tobacco result from other substances in tobacco.
