Methanol ne mai guba, wanda ya shafi jijiyoyin bugun gini da kuma juyayi tsarin. The yawan guba daga cikin abu saboda da hadawan abu da iskar shaka a lokacin da ingested da kuma tuba zuwa rai barazana formaldehyde.

Methyl barasa mai guba wanda zai iya faruwa bayan samun biyar zuwa goma milliliters sa makanta a cikin mutane. A kashi wucewa talatin grams, shi ne sau da yawa a cikin hanyar mutuwa, wanda ya auku a kan katsewa na numfashi tsarin, huhu edema ko kwakwalwa da kuma uremia ko auka.
