It was Friday night (last Friday) when I returned home from work and bought some weed to flush away my tiredness. After having my dinner and enough water as I always energize myself before smoking - I am quite lazy to grab water or food after getting stoned. Am not a newbie as I've been smoking for around 5 years but limited smoking to only weekends since the last year. There was a painful wound in my right underarm so I took a painkiller after dinner. Finally made a joint and started, this experience was for the first time as the very 2-3rd whiff got me feeling high or maybe it was just an exaggerating mind as I had been neat for the whole week, don't know! But I kept on as that was what I wanted. The joint was close to end but I knew I couldn't go on so I blew it and decided to dump it. The last thing I remember after completing the joint was the pain in my underarm as after the painkiller I couldn't feel the pain externally but it was terrific inside. Here is when it felt an uncommon high, as I stood up to dump the bud it felt little dizzy so I rested myself to the sofa and sat back there thinking I'm gonna throw up. Then I decided to go to bathroom to avoid waking everyone in my house by the 'hwuah' sound, I grabbed the keys and locked up my door and turned back moving towards my bathroom when I felt my feet immovable and in spite of my room lights switched on I felt all the darkness with my eyes open and fell to ground as I stood facing upwards and a pretty loud noise due to dropping my cellphone that eventually woke up my dad and sis. It felt like I was dreaming about my dad and sister rushing to me and asking me what happened. It took me 10 secs to sit back on my butt and still wondering as to what happened and why am I surrounded by both of them? After my dad helped me walk to my bed and lie down I was still nauseous and constantly high so I drank glucose with a little water to avoid throwing up the water I just drank. Finally I slept and woke up the next day remembering everything that happened the previous day but having no idea why. This is the first time I ever fainted down. Did the painkiller-marijuana mixture faint me or was it something else I should know?
