It's not a semantic argument. It's important to make it plain, before having a reasoned discussion, that there are legal drugs that people use every day but wrongly categorizes as "not drugs." Alcohol, nicotine, and caffeine being the main culprits. Food, exercise, and social media also cause experience-shifting changes in neurotransmitters (the drugs that are always mediating your experience). It's important to get this straight before lumping things that are illegal into a poorly-conceived category.
While it is true that there are other substances that could and should be called drugs, it is not conducive to discussion to argue over definitions when it is clear people are talking about drugs colloquially. To bring up coffee serves no purpose other than to derail the comment thread - as it has.
Air also causes experience shifting changes in body. Think of the last time you went without it. Also thoughts cause multiple experience shifts during the day. Maybe we should start be controlling the air and eliminating thoughts before we get to these bigger things?
everything does. it's a question of individual context, individual biology, and what you define as "experience-shifting" + our ability to understand and measure the human brain.
