Not true, according to OPCW. Rebels are suspected (primarily Al Nusra) of being responsible for 2/3 of all chemical attacks so far, and numerous makeshift chemical weapon workshops have been found in Al Nusra held area so far after liberation. There have been reports of Al Nusra manufacturing low grade sarin in Iraq and moving it to Syria (google news reports from 2014, 2015 and 2016). Chlorine is apparently much more easily available/manufactured.
