I am 15 years old , and i wan't to try some marihuana (joint),, I am reading for 2 days and i see that it is not that unhealthy for one time .. I just wan't to feel relaxed and feel good , but ofcourse , getting afraid of my parents.. so , if i smoke it , and if i come home some hours later , would my eyes became red? would i lose my mind ? Will my parents understand the situation?
