Vancouver Coastal Health has issued a public alert after drugs on the Downtown Eastside tested positive for benzodiazepines, a tranquilizer-type drug creeping into the street supply and causing grave concern for health officials in B.C.

A substance dubbed 91裸聊视频済reen down91裸聊视频� was found to have fentanyl and a kind of benzodiazepine in it at one of the overdose prevention sites and supervised consumption site on Wednesday, according to the latest alert sent by Vancouver Coastal Health.

The class of medication, commonly called benzos, includes drugs like valium, ativan and clonazepam. Overdoses caused by such drugs cannot be reversed by the naloxone, the .

Dr. Mark McLean, medical lead of the Rapid Access Addictions Clinic at St. Paul91裸聊视频檚 Hospital, told Black Press Media that the drug was first prominently found in Vancouver91裸聊视频檚 street drug supply in early April, and when mixed with illicit fentanyl creates a deadly cocktail that91裸聊视频檚 proved difficult to combat for frontline workers and emergency officials.

91裸聊视频淲e don91裸聊视频檛 know why that class of medication is creeping into the drug supply,91裸聊视频� he said.

Vancouver Coastal Health said its received numerous reports of overdoses caused by people who thought they were consuming opioids, but instead are ingesting illegaly manufactured flualprazolam and flubromazolam as well as benzodiazepine analogs such as etizolam. In some cases, drug users are intentionally taking the latter.

It91裸聊视频檚 possible that drug dealers are spiking their illicit supply to essentially fool the customer into thinking they are taking opioids, specifically using a drug that mimics both the desired effects and side effects of opiates, McLean said, adding that is 91裸聊视频減urely speculation on my part.91裸聊视频�

Opioids are known to create a calming or anti-anxiety-type effect, and a feeling of relaxation. While benzos such as clonazepam are commonly used to prevent and control seizures, they generally slow down your central nervous system like a strong sedative and have been used as date-rape drugs.

91裸聊视频淭o a large extent the drug supply is unpredictable as to what it contains, and that unpredictability is why we are having so many overdose deaths in the province,91裸聊视频� McLean added.

There were 462 overdose deaths between January and May 91裸聊视频� the most up-to-date data available. That91裸聊视频檚 compared to 651 deaths during the same time period in 2018, when B.C. saw a record-breaking number of drug fatalities.

Benzos entering the street-level market are becoming a concern for health officials, as B.C. starts to see a plateau to the number of monthly overdose deaths, a slight reprieve that has left the BC Coroner Service cautiously optimistic.

91裸聊视频淚t turns out that when opioids and benzos are combined, that combination can cause a more severe kind of overdose,91裸聊视频� McLean said. It91裸聊视频檚 unclear how far-spread the deadly cocktail is in B.C., but has been confirmed in Vancouver and Powell River.

The mix causes sedation and respiratory depression through separate pathways in the brain, according to the health authority. In combination, these drugs act synergistically to worsen sedation and decrease the drive to breathe.

While overdoses can be caused by all kinds of illegal or prescribed drugs, doctors and nurses have limited options when treating someone reacting poorly to benzos.

One of those options includes flumazenil, but that91裸聊视频檚 much trickier than naloxone, McLean said, due to side effects being more sensitive to dosage and possibly causing seizures if the person has grown dependent to the drug.

91裸聊视频淲e are still at a stage where we are trying to figure out exactly what to use in these types of overdoses.91裸聊视频�

What to look for in a benzo overdose

Overdoses from opioids or benzos are somewhat similar, according to health officials. This includes slurred speech, lack of coordination, difficulty breathing and drowsiness. Lack of oxygen will cause the skin to turn a 91裸聊视频渄usty colour,91裸聊视频� and fingers and lips can turn blue.

If you see someone overdosing, you are urged to call 911 and those trained should administer naloxone. If the overdose is caused by benzos, the person will need to be monitored by trained health professionals for several hours or longer.
