patient / motor vehicle operating laws

I'm a new patient being treated for PTSD and IBS, and I work a 8-5 desk job. I've been wondering how the laws work around this. I have to medicate within an hour of waking up most or all morning due to my IBS, and so I'm obviously pretty medicated driving to work and my truck always reeks of good herb. I'm just wondering if I am risking getting an OUI? I would think so? I've been smoking for 10+ years and have a very good tolerance, so I've never felt like my driving was a problem and I've never been in any accidents or anything like that. I know some states say you're not allowed to drive if you even have some in your system, but we all know it would take a long time to clean our system out. I'm currently in the process of making alternative forms of medicine (cannacaps, oil) so I'm hoping I won't have to worry about it while I have an alternative to flower, but I pretty much have to make all of my own stuff like caps when I need it because there's not much for a patient network in the county. Anyone? What's your opinions on medicating at work also? My boss is understanding and he's also my cousin who I've smoked with once or twice, so that's not really an issue here.

I would get a vape Pen and use that like a e cigarette. They make some pretty good models now days. It won't get rid of the pontential OUI but it will help with the smell and is real easy to use for a quick session.

Or a good brownie with lunch would be a good choice.

Yeah the vaporizer wont stink as much as smoking.

I know in colorado they have things now pretty much like breathelizers. But not sure in maine. Not sure where you are in the county but they have these cool vaporizer globes just a little glass ball, ceramic heating element put dab in, hit a button toke, noone knows they're neat. If your in the presque isle area rmj's has them for like $40
