That is a question. And of course when asking if someone 'can', the answer is usually yes.

however, it doesn't mean that a person WOULDN'T be absentminded without marijuana.

I can function normally, and I do. Potheads hate to argue! I was on a self propelled 155 howitzer that was nuclear capable. I was an assembler of the nuke all of this high. And yes I drive high, I dont drive absentminded. I drive with caution and obey all traffic laws. unlike the sober idiot who passed me yesterday doin 60 in a 30 with thier 2 babies in the back. I know they were sober because they were heading to the church accross the street from where I was going! Another thing is I am about to change my fan belt on my jeep. It says to shut off the engine first. I know they didnt put that dumb label on for us potheads!
