1. If any intoxicant is thin and flows, whether it be alcohol, toddy (an intoxicating drink made from palm juice) or anything else, and by drinking a considerable amount of it one becomes intoxicated, then even a single drop of such an intoxicant will be harâm even if one does not become intoxicated with such a meagre amount.
Similarly, it is also not permissible to use it in any medicine irrespective of whether the medicine is in the form of a syrup or in the form of an ointment. And irrespective of whether the intoxicant remains in its original form or whether its form changes due to certain chemical reactions. From this we can gauge the impermissibility of modern medicines in which alcohol is found in most of them.
2. As for that intoxicant which is not thin and flowing and is instead a solid, such as tobacco, nutmeg, opium, etc. the rule with regard to this is that the amount which intoxicates a person or causes him severe harm will be harâm. As for that amount which does not intoxicate nor does it cause severe harm, that is permissible. If it is used in an ointment, plaster, etc. there is no harm in this.
