Garlic Gas reminds of ild school skunk weed circa 1977. Afgani or skunk had a definite sulfur earthy smell and taste. Potent in every puff, coughing may occur as creeper high engages the user.
I have smoked this strain or similar strain in Gainesville Fl circa 1977. I never forgot the unusual fruity pine aroma of buds in a mason jar. Seems this hybrid has one parent of either Columbian Gold or Acapulco Gold and purple thai maybe.
