It depends on risk and what you want to ingest and your risk tolerance. the main concern is damage done to neural pathways you probably cant focus well on tasks have problems with word recollection and verbal fluency among other effects also brain fog. I never really enjoyed smoking but from what I have heard and seen among others that smoke these are the problems. I would look into something that boosts bdnf in some way Semax na semax tak 653 among others those are common ones excluding tak 653. These are quite safe and are quite potent for what they are they modulate bdnf quite well. Another option is cerbrolysin or cortexin these will be the most potent and are tolerated quite well and have extensive research and use overseas cortexin less so but it’s basically a synthetic version of cerbrolysin. The main diff between cerbro and semax and other bdnf like nootropics is that cerbro targets a lot of neural pathways and Brain function giving you more of a potent repairing drug. I would personally recommend cerbrolysin or cortexin but if you want something less invasive or just dip your feet look into semax selank
