 Great person
How long do you have to wait? (If there is no effect from different types of tobacco products)
Recently I started throwing snus (Swedish tobacco, which you need to throw over your lip and wait 5-30 minutes), now I feel that the effect is 0, not a blow to the head, not relaxation, even a cigarette is no longer coming. How long do you have to wait without tobacco products for the effect to return? I ask without answers: nicotine is harmful!!! you are ruining yourself!! I xs, I think this is harmful!! harm!!
