As for wanting money instead, it could also be (and is) used for thousands of different reasons other than drugs. It
could be used for transportation, or shelter, or clothing, or hygiene items, or home supplies (furniture, appliances, utensils, books, tools, etc.), or medications, or rent, or cell phone minutes, or birthday gifts, or toys for their kids, or services (haircuts,
legal services, medical services, etc.), or helping out a friend or family member, or replacing items that have been broken or lost or stolen from them... the list of things everyone needs money for in this society is endless.
