DENVER — Chris Easterling was sick of relying on drug dealers in Minneapolis when he needed marijuana to help ease the pain of multiple sclerosis. They were flaky, often leaving the homeless man without the drug when he needed relief the most.

So he moved to Denver, where legal pot dispensaries are plentiful and accessible.

Easterling is among a growing number of homeless people who have recently come to Colorado seeking its legal marijuana, and who now remain in the state and occupy beds in shelters, according to service providers.

While no state agency records how many homeless people were drawn by legal weed, officials at homeless centers say the influx they are seeing is straining their ability to meet the needs of the increasing population.

“The older ones are coming for medical (marijuana), the younger ones are coming just because it’s legal,” said Brett Van Sickle, director of Denver’s Salvation Army Crossroads Shelter, which has more than doubled its staff to accommodate the increase.
