This very common question is very well know by those that have tattoos or are getting a tattoo. The common answer to this common question is yes you can but, not much. It may lower the pain associated with getting tattooed, but drinking many drinks or having a heavy night with alcohol the night before getting tattooed does affect the result. This is caused by two reasons, one is alcohol is a known blood thinner, and also this excess blood can dilute the ink when getting the tattoo. This will cause the resulting tattoo to be slightly faded or blotchy. So, no it would be wise to say DO NOT DRINK before your ink.!
