I could walk, just not very well. However, I HAVE been high enough that when I closed my eyes while standing up I tipped over and fell flat onto my back. Slammed my head pretty hard too.
i once got so high that i fell while walking up stairs, then layed there for ten minutes because i felt like i was sinking into the ground.
Ive been really high before (read several yrs ago when I was a new smoker and got way too high and couldnt deal with it high) but its never effected my coordination in any major way.
this one time i got really high and it took like ten years to get to the top of my stair well then i think i forgot something and when i turned around like halfway up the stairwell then stairs were like moving and i misjudged the steps and fell down like 6 not alot but still.
Highest I have ever been was when couldn't see how much smoke in bong chamber (night time) and kept the lighter on, burned the inside of my lungs and wound up in fetal position rocking in pain for almost an hour, stoned out of my mind. Extreme pain + being stoned= FUCK ME
no amount of marijuana has ever made me not be able to walk or stand... and this is not from lack of marijuana... if i've ever fallen over or not able to walk.. i was more than stoned
Only if Im smoking indica and Im super super high. Sativa makes me move more "gracefully" if you will, I generally dance around if Im moving. Sometimes if Im smoking nice indica Ill stand up and realize that I can't really walk so I sit back down or just stand their for awhile (if im smoking in a creek). Its always an adventure trying to get out though
ive gotten a crazy head rush before right after smoking a couple bong bowls and i fell right back onto my bed but ive never had a problem with walking unless i was drunk too
