MONTREAL - Hockey legend Guy Lafleur was fully aware his son was doing hard drugs while living with a teenage runaway, the now 19-year-old woman told a Montreal court Wednesday.

Mark Lafleur, 23, is being tried on two counts of sexual assault after pleading guilty to 14 other criminal charges on Tuesday.

Under cross-examination by the defence, the alleged victim acknowledged she was a heavy drug user while dating Mark Lafleur between 2004-2006.

She said they both took ecstasy on a daily basis, while also occasionally doing cocaine, GHB and crack.

The young woman said Guy Lafleur knew about his son's lifestyle and was aware she was in poor health.

She testified she weighed only 66 pounds when her relationship with Mark Lafleur ended.
