Drugs affect our body. People these day are doing more drugs. The drugs affect the brain,the heart, and are movement. When the drugs go in to are body, the drugs kick in and mess with our brain. Then people that do the drugs get addicted. Then they cant stop doing the drugs. It's like when people smoke, the cant stop. But people can stop, it just takes a-bit of time to stop. People can stop smoking too. I know some family members how smoke. Just tell them to stop, encourage them to stop smoking/doing drugs.
