words - Is שכרות in the Talmud (or other rabbinical sources) limited to alcoholic substances?

In many places in the Talmud the word "שכרות" is used (Shabbat 10, Beitzah 4, etc.) in these places is it proper to understand it as referring to alcoholic beverages (the simple/common translation?), or would it include other substances as well (i.e. marijuana, cocaine, etc. etc.)?
