While I wouldn't recommend something this risky & self-destructive, I imagine the feeling of being honestly desired, the experience of women wanting to talk to you, wanting you to come to their party, seeking your attention, etc. is probably quite intoxicating. They might only be there for what you can provide, but in a sense that is always the case. Be it money, status, fun or even high quality genetic material, there will always be some amount of disconnect between you and the vocal point of her desire. The distance between the two might be larger with something external and widely available like drugs, but it would still be better to be desired for something you provide rather than not be desired at all.
The dealer whos story I was looking to post was blackpilled by how transactional the whole sex / affection part was treated by these women and he became more unapologetically selfish in his relationships afterwards. Experiencing something like that for yourself doesn't have to be a purely negative influence on the rest of your life.
Trading sex for drugs is not only happening with low life addicts, upper middle class girls / young adult women are also looking for some fun and I suspect many of my former classmates have made such an exchange at some point in their life. These girls were reasonably wealthy and clean, they would never have fucked you for money (unless you would overpay by orders of magnitude), but if you had drugs and were at the right place at the right time you could have gotten a chance with them.
Again, I don't think dealing drugs is advisable as an ascension plan or in general, but it has some benefits that are hard to deny.
