This is a tale of two friends. After smoking weed for about 2 years daily nothing even close to this bad was happening now weed has virtually no effect. After those two years the two friends had to switch to legal alternatives for employment. At first the hits lasted as long as weed but were more potent. About 3 bowls were being shared daily. Tolerance levels quickly grew and the first head shop's strongest stuff wasn't good enough (snip).
Soon spice became more desireable than weed and switching back just seemed stupid because random piss tests werent uncommon for work. The hunt was on from brain eater to cranium until the ultimate shop was found. Splitting 4g in a bong of the snip or snip became the daily norm after 2 or 3 months in and then 5g of the most potent spice locally known, snip. By the end of the next month either person could put down 5g of the snip themself in a day.
At this point thinking there may be a slight issue the internet was searched. People detoxing werent even coming close to this rate of consumption and reality had set in. Cold turkey was not an option when your body would wake up after being asleep only 2-3 hours before needing another hit.
One friend weened the consumption down while the other fiend until his last dollar was spent on it. His brain was turning into mush/zombified but he was in denial. The vast majority of his day was spent smoking until passing out. Sometimes he would take too big of a hit and throw up only to hit it again within the hour.
If you get that far in its not so easy to stop. Urine would turn cloudy and feces tarry but rarely discolored. Chest, stomach or intestinal pain would be experienced at least once a day. Tryptamines with spiritual experiences warned them both to stop but the one has continued. This stuff is nuts at this level and wouldnt be suprising if truly deadly. Prison might be a better option i wouldnt recommend anyone picking it up because it can turn out of control quickly. Expressing concern for the health of the friend addicted is laughed off and seems hopeless to try and help.
