DAILY DOUBLE!
Please explain, using science, why avoiding drugs and alcohol is important in increasing emotional health (how does it affect our brains, and why do we feel so crappy after?)
What is because when using substances, our brains receive a ton of dopamine/seratonin/"feel good" chemicals. But, after those chemicals leave our systems, it can cause anxiety/sadness/lack of self worth/etc because our brains are not producing the "feel good" chemicals. However, physical activity and good experiences with friends are some of the best ways to NATURALLY create more of these chemicals.
