Well... it may happen indeed, but it would require a LOT of heating... alcohol evaporates at about 170F and THC starts to evaporate only at about 300F, so its a great interval of temperature between them... and before the THC evaporate, the hash oil starts to bubble, so its easy to notice when its being over heated... anyway, heating the tincture in a water bath ensures that no THC is lost, as the highest temperature that a water bath reaches is 212F, far below the temperature needed to start to evaporate the THC.
