Dhamma cannot go together with the use of intoxicants. If you really wish to develop in Dhamma, you must stay free from all intoxicants. This is the experience of thousands of meditators. By drinking even a small amount, in the long run you develop a craving for alcohol. You don't realize it, but you take a first step towards addiction, which is certainly harmful to yourself and others.
Every addict starts by taking just one glass.
