One man is dead after a drug overdose and two Edmonton women were rushed to a Calgary hospital after taking ecstasy.

The 37-year-old man was found dead by emergency services in his Falconridge home Sunday morning at 7 a.m. MT.

Two others, a woman in her 50s and another man in his 30s, were taken to Rockyview Hospital as a precaution.

The trio took a number of drugs, and told emergency services that ecstasy was among them, said EMS spokesman Stuart Brideaux.

Calgary police said Friday there have now been six deaths related to ecstasy mixed with paramethoxymethamphetamine (PMMA) in Calgary since July. PMMA is a type of methamphetamine.

Edmonton women bought ecstasy in Calgary

The two Edmonton women, both in their 20s, were in Calgary this weekend where police say they purchased the drug.

The women were at their downtown hotel room at the Ramada Inn on 8th Avenue S.E. Saturday when one of them called 911 at 6:30 a.m. MT.

They had been at the Republik Nightclub earlier that night.

Both were taken to hospital, one has since been released.

The other is in serious but stable condition.

"With what’s going on in the current events, taking the drug is an absolute roll of the dice," said Brideaux.

"We’ve also had people who have been very, very sick, in critical condition in the hospital."

In those cases, many will never fully recover, the EMS spokesperson said.

18 have died in B.C. in last 6 months

Police warned Friday the batch of laced ecstasy is not likely from a single source, but they are similar.

"There is a common link in that we're seeing powder associated to the deaths that we are dealing with, so a powder form of the MDMA and PMMA," Staff Sgt. Mike Bossley said Friday.

In B.C., another 18 have died after taking the drug in the last six months, and a 19th death is being investigated.

RCMP in the Northwest Territories warned the public about the drug Friday.

Police say the user might experience hyperthermia, hypertension, agitation, confusion or convulsions.

Anyone who has taken the drug and experiences these symptoms should seek immediate medical attention, urged emergency services.

Ecstasy is usually distributed as a tablet, but can also be found as a powder or in a capsule.
