i dont think gbl is illegal since its used alot in industrial factorys, but it could be made illegal in the US, i think i have read that somewher on a site who sells gbl and were not allowed to send to America but im not 100% sure.
and why are ppl converting GBL to GHB when GBL is ingested, your body converts it to GHB?
unless you are going te sell it ofcource, then you beter convert it to GHB for safety reasons.
i use GBL about once in 3 days, it helps me a lot with my social anxiety, wich i been suffering from my whole life

.
i have stoped using daily because the withdrawls are horrible when you suddenly stop using, they take about 3 days to fully wear off, the shaking is the worst the first day, then comes the anxity wich is horrible and lasts 2 days and your still shaking a bit and you are also nervous.
oh yea i forgot to say your also feeling depressed and thats not worth it imo.
i have read on erowid from ppl who have used GBL much longer and high doses who had to been put in a psychiatry after quiting there GBL adiction.
there withdrawls where even worse, hallucination, aggresive, and alot more nasty thing you dont want to have, so pls be carefull and so some research.
but i could have found a way of using GBL daily with no withdrawls, very small doses for a long period could do the trick (i have done this for a month and 2 weeks, i cant say if this is also the case when you use it any longer) i stoped from one day to the other and i didnt had any withdrawls at all!!
i think for some ppl with mental problems, if used in the right way, this can be a good medicine (anxiety, depression, restelsness, hard time falling a sleep, etc...) .
you have to measure your doses carefully though, cuz its alot less that you need to feel the effects compared to GHB (i think its about 1/3, correct me if im wrong), and it takes a while before you know to redose and not to overdose, and this happens alot with gbl wich isnt so good when your at a party

. but its not a party drug imho, i use it more for relaxing with some friends or as a medicine for my social anxiety.
when i first started using gbl it took me 4 weeks to know a good dose and when my body can have another dose, i have passed out many times in this period, but thats nothing to worry about, you will be very awake and alert after 3-4 hours like you had a good deep night sleep

.
i also think that gbl has a more aggressive high and kicks in faster and takes longer to wear off then ghb, but that is from my own experiences. (i have used both)
ive been doing this for over a year and i dont seem to have any medical or mental problems with my organs or anything else.
just make sure you use a full big glass of orangejuice or some other soda (something with oranges will take almost all that nasty chemical taste away) and you wont damage your throat or any other organs.
