i'll try to keep this brief ... started smoking because of migraines, but i've always had lung problems. most recently, this is the second year in a row i've had to deal with pneumonia (last year i was hospitalized for a week). i don't smoke much -- only what is effective ( usually ;-) ) and only when i start getting a migraine. it's seriously a miracle drug though. i'd tired everything from maxalt to imatrex and even topomax (an anticonvulsant) among other things. combining daily topomax with maxalt when i'd start to get a migraine would work but i'd still be out of my mind for 2 days and the topomax side effects were not worth it (one is that you can't find the words you need to say something, and i work as a writer ... so you can see how that'd be a problem). cannabis, on the other hand, will completely eliminate a migraine in less than 5 minutes with very few side effects, allowing me to actually get work done and go about my day normally. it's a god send. anyway, there are issues. i built a double bubbler bong with an ice chamber and a filter in the down stem out of gatoraid bottles, plastic tubes, and a rather nice wooden pipe. i keep things clean and don't heat things that will hurt me (no aluminum foil or anything). it's a bitch to use, but i'd hope that there was enough filtering going on to keep my lungs safe. but it seems that smoking is really starting to affect my lungs in a bad way. this is the first time i've had pneumonia two years in a row, and i can't think it's just coincidence. i started looking into vaporizing a few weeks ago, and i'm abstaining until i can get my hands on a vape ... but i hear they still don't filter everything that not lung friendly out. to this end i'm hoping to add a water bong to the end of a whip vape ... but do you guys think that'll do it? will i need to go further to filter things? does anyone else have lung issues and still smoke/vape or am i totally screwed? before anyone mentions it, eating the weed actually doesn't have the same effect on my migraines so it isn't really an option. actually, i'm a little worried that vaping won't have the same effect as smoking either ... but i've gotta try it. anyway, there's another issue. while i don't live in a medical marijuana state, my doc is working closely with me to try and help me do things to prevent migraines (which has definitely helped reduce the number i get, but hasn't solved the problem). she knows that i smoke to treat the migraines, but is worried about other aspects of things. my doc says that cannabis usage can unbalance your hormones -- we did some tests and my testosterone (and something else i can't remember) is too low and my estrogen (and related hormones) are too high. (i'm a dude, so that's not really good). she says that this could contribute to my lack of energy and some other health issues. i'm just wondering if any of you guys have had to deal with hormone issues because of cannabis use, and if so, what's a good way to do that? thanks.
