Riot SquadPurple Burst Nic Salt e-liquid serves up a refreshing blend of tart blackcurrants and sweet slush. The inhale delivers a juicy burst of sweet and tart blackcurrants, followed by a wave of icy slush. Riot Squad Salts use a hybrid of freebase and salt nicotine to deliver the quick nicotine fix but with a more noticeable throat hit.
