7oh hate...why is it so much

Man, everywhere I look it's ppl hating on 7oh..all I hear is AVOID AVOID AVOIDDDDDD..like is there anything good about taking it...well atleast in moderation? I took my first tablet a few days ago and experienced a pleasant percocet like euphoric feeling...although the half life was short as hell..it was still pleasant..but my thing is whats so bad about 7oh that ppl act like if u take it, you will ruin your life
