Smoking drugs does not make people older. Rather in multiple studies smoking can cause lung cancer. It can also cause tooth loss and infect the throat. It can also make you more nervous than you already are.
drugs should not be forced onto other people. Nor should it be a norm to be in a friend group. Not only does smoking drugs make people high but it also affects the brain. Some ways it can affect the brain is by making them addicted to the drug and not able to function without the chemical.
Although drugs can calm you down it can also affect your brain. It can interfere with the way neurons are sent, received, and process signals through neurotransmitters. But a thing to keep in mind is, that when people are physically addicted it can make your body not able to function without the drug.
Smoking is bad enough but smoking drugs is way more dangerous. Cigarettes have nicotine which is addictive. It also has tar that can cause the blackening of lungs. Although some drugs have the ability to calm the nerves it can also kill the nerve that is being controlled. In this case it can disturb the normal function of the brain.
After all is said and done, I think it should be recognized that smoking and taking drugs will harm you mentally, physically, and emotionally. It is never worth to damage yourself in an irreversible way. So I hope that you have learned enough to not let yourself into temptation.
