Helena, Mont. ? General rule of thumb: when looking to buy marijuana, don’t text the sheriff.

Authorities say a Helena teen sent out a text message last week in search of pot, but instead of contacting the drug dealer, he hit a wrong number and inadvertently sent the message to Lewis and Clark County Sheriff Leo Dutton.

The text read, “Hey Dawg, do you have a $20 I can buy right now?”

Dutton told the Helena Independent Record he initially thought it was a joke, but he quickly realized it was a real request for drugs. He responded to the text, and a detective pretending to be the dealer organized a meeting with the boy last Wednesday.

“The kids knew that they were going to be at a particular store at a particular time,” Dutton told The Associated Press.

No citations were issued after the parents of the boys, who were 15 and 16, got involved.
