Get nicotine gums and stop inhaling any kind of smoke or vaping. Tobacco is to never be inhaled, that is guaranteed death. The practices will help to cease this habit, at the same time some stimulation will happen and your emotional attachments to these can challenge you a lot. This is because smoking embeds in memory, behavior, and the structures of the brain. You are looking at a few months of reorientation with the nicotine delivery, a period of relaxation, and ease to quit nicotine as well. Addiction to nicotine is different than the behavior addiction you have to inhaling smoke. As you cease the smoking part, this is one layer, while the nicotine is the last one.
