"the canadian government has banned w-18, the powerful street drug routinely decried as 100 more times stronger than fentanyl - but critics say critics say it might do more harm than good in the battle against opioid overdoses across the country."
"on top of that, experts are questioning the science behind the governments alarmist claims about just how potent it is."
"while the statement from health canada on wednesday goes on to use the typical characterization of w-18 as a "synthetic opioid" that is "extremely dangerous and can be 100 times stronger than fentanyl," a number of drug experts say this might be inaccurate."
"brian roth, a pharmacology professor at the university of north carolina conducting a study of w-18, told the calgary herald there is no scientific evidence that the drug is even an opioid let alone that it is 100 times stronger than fentanyl."
" 'as far as I have been able to determine theres no scientific data on the compound other than this single patent. and in the patent, its really impossible to determine much about the compound' said roth. 'it could be a dangerous drug. we don't know'. "
"health canada did not immediately reply to a request from vice news regarding its evidence on w-18. one of the first claims that w-18 is '100 times stronger than fentanyl' appears to have been made by the calgary police in january of this year following a seizure of the substance."
".. british columbia provincial health officer doctor perry kendall takes a different stance and says that criminalizing w-18 will likely not make any difference"..."he would prefer to see the government focus more on reducing the overdose problem instead of criminalizing illicit substances."
"he pointed to france, where he said general practitioners can prescribe suboxone as an opiod replacement. 'this has reduced overdose deaths by 80 percent' said kendall. 'but here in bc, that ability to prescribe it is limited to a certain number of doctors.' "
"portugal is also a good example of a country that has limited drug addiction and deaths, he said. ' there, they have decriminalized all drugs, and when you compare it to other countries, it has far les overdoses than countries like canada where we have focused on making substances illegal. but this sort of shift in policy would require time.'
