Tancredo bet a documentary filmmaker that if Amendment 64 passed - which legalized recreational marijuana - he would smoke pot.

Heoriginally saidthat he would honor the wager, but in an email Friday, he stated he will have to "welch" on the bet.

The email reads in part:

"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."

Tancredo supported Amendment 64 but said he made the betbecausehe believed Colorado voters would note pass it.
