alright so me and my friends were in france and we went to buy a rolling paper in a smoke shop. once i went in i immediately saw the weed and asked for a little. got 2.5 for 20euros which i thought its expensive but didnt ask what it contains. once i got home i saw its hhcpo (10%) and h4cbd (10%) mix thank god i found it. i was going to smoke .5 but i only did at most .05 and it was very enough. got a good buzz from h4cbd first and than about 1 hour later got the psychoactive effects of hhcpo. day after: im still high and it was hard to wake up after 8 hours of sleep. conclusion: good shit! make sure you use cig filters to filter ketene. also, only use verrry small amounts
