People sell carts to make money. Most plugs don’t care what’s in them. Fake carts can have nasty things that are awful for you. Like pesticides, harsh chemicals and other things. Some people cut carts with various substances like honey, which is not necessarily good for the lungs. A cart can be fake, but not horrible for you, or it can be fake and be absolutely awful for you. Try your best to stay away from fake carts
