Oregon marijuana shops began selling marijuana Thursday for the first time to recreational users, marking a big day for the budding pot industry.

Some of the more than 250 dispensaries that already offer medical marijuana in Oregon opened their doors soon after midnight – just moments after it became legal to sell to anyone who is at least 21.

At Portland’s Shango Premium Cannabis, co-founder Shane McKee said the first sale to an excited customer came about a minute after midnight, with many others waiting.

“It looks like there is about 60-70 in line out front,” he said in a telephone interview shortly after midnight. “They all seem extremely eager.”
