Hey everyone! I will be talking about the negative effects of decriminalization and the negative effects of marijuana.
Why could decriminalization be negative?
People who are biologically more likely to be addicted may experiment with drugs more if it is legal. One of the reasons for this is because they will not fear legal prosecution. If something has no legal consequences, individuals are more likely to try it. 
If addiction rates rise due to this, we would not have the resources to help patients. 
In the past few years, more and more youth have been using marijuana. The rate of 12 graders who smoke marijuana has increased by 24% each year. Teens have been more open to trying it and are not as scared as they used to be. In addition, marijuana is becoming easier and easier to find with decriminalization. What are the health effects of marijuana on youth? The main effect is increased risk of psychosis and schizophrenia. 
A fact that absolutely shocked me? Teens who smoked weed at least five times were TWO times as likely to develop psychosis in the next ten years. If you are already at risk, that risk will double. A teen who has a family member with psychosis has a 1 in 10 chance of developing it, even if they do not smoke, if that teen smokes marijuana (at least five times), that risk increases to 1 in 5 chance. So, the kid who had a 10% chance of developing psychosis now has a 20% chance.
