The lawyer for a sports doctor who has treated Tiger Woods says the superstar golfer is in no way linked to the drug-related conspiracy charges Dr. Anthony Galea faces. Galea, 51, is facing four charges related to the unapproved drug known as Actovegin. He has been charged with conspiracy to import an unapproved drug, conspiracy to export a drug and smuggling goods into Canada. His lawyer, Brian Greenspan, said Friday that those charges are in no way related to Woods. Greenspan says Actovegin is used worldwide and there was nothing unlawful about Galea's use of the substance. Actovegin, which contains calf blood, has stirred up controversy over its efficacy and legality. It's not on the list of banned substances for the World Anti-Doping Agency, unless it's used by intravenous infusion.
