Stay far away from drugs and alcohol; they will destroy you financially and in many other ways. So many careers have being sacrificed over beer, wine, vodka, etc. Drugs and alcohol are deceptive and dangerous and only makes fools of those that consume these poisons. It is not necessary for you to personally figure out the effects of alcohol on finances, there are enough examples in society to prove how fast one can come to poverty by using these two substances. How often do you see a person making some very foolish decisions in various aspect of his/her life only to realize later that they use one or both of these substance. Here the Bible is very clear.
Proverbs20:1 Wine [is] a mocker, strong drink [is] raging: and whosoever is deceived thereby is not wise.
Proverbs23:20 Be not among winebibbers; among riotous eaters of flesh:
23:21 For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe [a man] with rags.23:29 Who hath woe? who hath sorrow? who hath contentions? who hath babbling? who hath wounds without cause? who hath redness of eyes?
23:30 They that tarry long at the wine; they that go to seek mixed wine.
23:31 Look not thou upon the wine when it is red, when it giveth his colour in the cup, [when] it moveth itself aright.
23:32At the last it biteth like a serpent, and stingeth like an adder.
23:33 Thine eyes shall behold strange women, and thine heart shall utter perverse things.
23:34 Yea, thou shalt be as he that lieth down in the midst of the sea, or as he that lieth upon the top of a mast.
23:35 They have stricken me, [shalt thou say, and] I was not sick; they have beaten me, [and] I felt [it] not: when shall I awake? I will seek it yet again. The sad end results of being under the influence is seen in spousal abuse, DWI, birth defects, failed homes, abuse children, slow thinking, slow movement, youth waste, etc.
