Question: which is the worst drug?

Hey there Medeina, its tricky to answer but the most addictive drug appears to be Heroine. It is a chemical that acts like a false signal inthe brain and trains the brain to alter our behavior so we will look to take it again. Heroine as a chemical drug actually blocks the brain cells that usually tone down our responses to pleasure. Normally the brain’s job is to let us plan our actions and understand the consequences, but Heroine and other drugs interrupt how the brain does this. They tell the brain chemically that taking them is the best action to do, this is why they are dangerous and they can cause long term changes in how the brain comutes what we should and shouldnt do.
