Is it wrong to sell items on internet sites on Shabbat? Even if I don't work? The sites punish ads canceled on Shabbat.

Question
Hi. How can a religious jew have an online business which has customer service available on Shabbos? From what I've read online, one can start the company together with a non-jewish partner who will take an eighth of the profits, but it seems that one must be careful that it should be a 'real partnership' - not sure what that means. Does this include decision-making? What if I outsource the basic level of customer service? Would that work? Thanks for any pointers on this.  

Question
Hello, a question i have if you don't mind is regarding "sorcery". What exactly is "sorcery"? In Greek it is "pharmakia" and that sounds like "pharmacy". Also if you look the word "sorcery" up in a Strongs concordance where it gives you the Hebrew definition for the definition, it uses words like "drug" and "poison". I've also heard people talk about how things like cannabis a mind altering drug can open your mind up spiritually to demons, and also how some use mind altering drugs to communicate with spirits/demons. I've also seen a rabbi that said cannabis was kosher and ok to use, and have heard of rabbis saying that medication is ok. So idk. I'm trying to understand. If sorcery does have to do with drugs does that mean certain types of drugs or all drugs? Only mind altering drugs? Or only all man-made drugs including pharmaceutical medication, hence pharmakia? Is cannabis ok to use/smoke? Are psychiatric mental health medications ok to use? There may be a few questions in here which I am wondering, but mostly i want to understand: What exactly is "SORCERY" aka pharmakia? Thank you, I really appreciate this service.
