I didn't know that the drugs would harm me that much, and I learned that it tampered with my brain controls.
The drugs made me feel unwell, both physically and mentally, but I was so addicted that I couldn't stop.
If my friend didn't enroll me in a drug addiction group, I might have made more bad choices, and maybe even died.
The lesson I learned with my drug use was: do not use drugs because they can harm you. Stopping your use of drugs can save your life, like it did for me. Find hobbies and interests in other things that are more beneficial.
