Nicotine high is very heady and can be relaxing. However the body quickly develops a tolerance and nicotine is physically addictive, meaning that smoking turns from a relaxing voulentary experience to a entirely habitual one that does nothing for you but ruin your lungs really quickly. Most cigarette smokers start in very early teens, by adulthood they haven’t had a true nicotine high in years and chainsmoke out of physical addiction. Smoking weed is much healthier by comparison as the high is much ‘nicer feeling’ to me and is not physically addictive. Smoke is still bad for your lungs but can be mitigated with edibles or dry herb vaporizers. source: parents and many friends were chainsmokers and I picked up the habit for a few months in late teens.
