The answer to the question according to me is a "Yes" and a "No". Now I will tell you why this confusion arises! Hinduism is a religion which is based on mere faith, religious teaching and the natural powers that govern the existence of mankind and the universe. None of these factors are affected by "alcohol" or "alcoholism" in any way and hence, there is no ban on alcohol as such in Hindu religion. In ancient times, many Rajas and Maharajas, consumed alcohol and it was considered as a way of relaxing and celebrating. Not only this, many tantrics and sadhus use alcohol as an offering to the god and also usd it for certain rituals. Many Hindus even today, continue to consume and use alcohol is their day to day lives simply because they know that their religion does not prohibit them from doing so. Alcohol is also used as a solvent and medicine in Ayurveda and Homeopathy. Though there is no prohibition on consuming alcohol as such in Hinduism, the religion still propagates the harmfulness of this toxic substance and its side effects. One should just be careful and keep in mind that excess of anything is not good for the body. Other views are more than welcome!
