Marijuana is less harmful because, as a rule, it is smoked much less, even by heavy smokers. Plus, its smoke contains fewer harmful chemicals. It has also not been possible to establish a link between smoking cannabis and the occurrence of lung cancer, but this issue has not yet been adequately studied.
The smoke from it is more tarry than from tobacco, so ideally it is better to use a viper, or eat it in a special way. When smoking, it is better to use high-quality devices with good filtration and cooling of smoke, rather than home-made ones.
Systematic smoking can cause mental dependence. Also, when you stop using, there will be a mild withdrawal syndrome. Sweating, poor sleep, appetite, desire to smoke and other unpleasant effects. It takes 3-7 days. Complete withdrawal of THC metabolites from the body occurs in 4-7 days with unsystematic use. If you smoke a lot, THC will remain in the fatty tissues for up to a month. The very fact that THC is present in the body does not carry any harm. But the test for drugs will be positive.
Also, with frequent use in men, sex drive often decreases, testosterone decreases. Many have memory problems. This is expressed in the fact that you become absent-minded and forget what you wanted to do a few seconds ago.
Cannabis is a psychoactive substance and this should not be forgotten. If you smoke often and a lot, then the character, priorities in life, needs, habits can change. This is his main danger. The difference between medicine and poison in dosage.

Never before in history has there been recorded death from the use of marijuana, as a smoking agent, in contrast to cigarettes. Marijuana is also not a destructive drug, but you can just get used to it. You will not have withdrawal symptoms, but you will want to. Cigarettes contain many carcinogens and hazardous substances, while cannabis is practically harmless.
Resins are harmful in a cigarette, because it is because of them that cancer and other unpleasant consequences of smoking appear.
In medical (!) cannabinoids resins and other harmful substances, but I doubt that you can get such quality marijuana in Russia, even though it is used as a medicine in a couple of US states.
Smoking is evil and marijuana is illegal.
Harm - it can be different; if the use of marijuana affects more on mental health, then cigarettes "rape" the physiology ... In any case, both are addictive ... Breathe freely!
Cigarettes are definitely more harmful.
Let me explain why.
There is relatively little tobacco in modern cigarettes, and many different impurities, thus making production cheaper.
Thus if you smoke the same amount of tobacco mixture from Cigarettes and marijuana, then the harm from the combustion products of the tobacco mixture will be an order of magnitude higher.
If we compare cigars that are produced only from selected tobacco, and marijuana, then again, harm to the body from cigars will be an order of magnitude more due to the combination of the effects on the body of combustion products and nicotine
I don’t think it’s possible to compare.
It's just that the cigarettes we buy in the store, the ones in the pack, they are glued together in factories, a lot of excess is added to them, which actually has a bad effect on health.
And marijuana is usually smoked by twisting it into a piece of paper, adding a cardboard filter and gluing everything together with their own saliva. There is no glue, paper is usually made from rice. Natural, as they say.
