Marijuana can range anywhere from 2% THC (very bad schwag) to 20% THC (very good dank bud). I've even seem some strains advertised as 26% THC.

So, assume a strain that is 20% THC, and assume an average size joint has 1 gram of bud in it. 1 gram equals 1000 milligrams. So 20% of the 1000mg of bud in the joint would be THC. That means 200mg THC would be in such a joint.

Then the question is, how much of that THC actually makes it into your system? From the website below, it seems anywhere from 20% to 50% makes it into your system when a joint is smoked. So that would be (high end) 100mg. The website below also says smoking a joint with bud that has 2% THC resulted in an estimated dose 13.0 mg THC, so that seems about right.

I want to eliminate the sea-sickness, so I want to make sure to take as much as is needed to have that effect. I just don't know how much that is. I also don't want to be fried out of my mind with my father in law. Or who knows... maybe that would make the trip just that much more fun!

I guess what I'll do is maybe make some cannabutter with 1/4 of a gram of weed and eat it a couple hours before leaving on the fishing trip. With my weed, I'm thinking that would be around 20mg or so of THC... maybe more if eating it is more efficient then smoking it. Hopefully that would be plenty since some of the trials I've found saw effective nausea relief at 15mg dosages.

Then I'll bring a mini-lightbulb vaporizer with me and another gram or so of weed. Worst case, if I get nauseous, I'll just lightbulb vape a little in the bathroom and see if that helps. As long as I make sure to err on the side of not burning the weed, and hold my hits, I don't think I would cause any sort of smell by vaping in the bathroom. I could also have a little can of air freshener with me just in case.
