Mourners lit candles in Goldenhill Park last night as the 17-year-old's friends remembered her, one week after her death.
The sixth-year pupil at St Peter the Apostle High School lived in Duntocher.
The school's head teacher Linda Booth described Regane as "popular, hard-working and enthusiastic."
Police issued a warning about the 'Mortal Kombat' tablets which have been linked to four other people falling ill.
Regane's funeral service will take place at St Mary's in Duntocher on Thursday morning, before she is laid to rest at Old Dalnottar Cemetery in Clydebank.
