After making national headlines, former Republican Rep. Tom Tancredo of Colorado said Friday that he would not smoke marijuana, despite his losing his bet.

In a statement posted on his Facebook page, Tancredo noted he supported the passage of Amendment 64, which legalized the recreational use of marijuana in Colorado. He said the government had no right to prohibit substances like marijuana.

"I must admit, however, I was surprised that it passed," Tancredo continued. "In fact I had made a bet with a fellow who was doing a documentary about the campaign, that it would not pass. If it did, I said I would smoke (or at least take a puff from) a marijuana cigarette. I would also explain my actions were a result of a bet and not because I was condoning the use of marijuana -- because I do not."

Tancredo agreed to smoke a joint with comedian Adam Hartle in the trailer for "Grassroots."

He said Friday he backed out of the bet due to family concerns.

"Well this apparently has become a national story and I have received a great deal of mail about it," Tancredo explained. "I have also received quite a reaction from my family. I am especially concerned that the publicity may cause my grandkids to have to justify my actions to their peers and afraid that no matter how many times I say I am NOT condoning the use of marijuana, that that message will not get through. My grandchildren are extremely precious to me and I would never want to do anything that puts them in a difficult situation. Therefore I have told the film's producer that I will have to welsh on my bet."
