99% of all addicts are liars and thieves. This might sound unfair and even close-minded, but it's the truth. There are some exceptions to the rules, but they are incredibly rare. Most people are no match for their addictions. They will be driven to do things they would normally never have considered all in the name of getting high. Sad, but true. So if you're thinking of trying drugs, keep in mind that all the people you will be dealing with are likely to steal from you and lie to you at your own expense.
Do you not know that God entrusted you with that money (all above what buys necessities for your families) to feed the hungry, to clothe the naked, to help the stranger, the widow, the fatherless; and, indeed, as far as it will go, to relieve the wants of all mankind? How can you, how dare you, defraud the Lord, by applying it to any other purpose?
The bread which you hold back belongs to the hungry; the coat, which you guard in your locked storage-chests, belongs to the naked; the footwear mouldering in your closet belongs to those without shoes. The silver that you keep hidden in a safe place belongs to the one in need. Thus, however many are those whom you could have provided for, so many are those whom you wrong.
