What is it you think hydroxyzine is doing to "dry" you out? Marijuana does stay in the body for about a month, I think, as it has fat soluble ingredients that store in the liver. So it does say in your system for awhile, and even if it didn't, if you smoke it every day it's always in your system. But here's the thing -- you've been smoking for years, obviously nobody has ever told you they smelled weed on you, right? But I will tell you, as a former pot smoker a long time ago the smell of smoked weed does linger on your clothing. But it doesn't linger on you. You also use the term withdrawal, which is a term with a meaning I don't think you're intending to convey. That refers to side effects that occur when someone stops certain drugs, but marijuana isn't one of them. People do miss it if they stop after using it for a long time, but it's not an addictive drug nor does it have physiological withdrawal effects. Some people confuse the lack of feeling high and reduced enjoyment for a time when you stop, but you would feel that if you stopped anything that enhanced your pleasure. You also don't "withdraw" from a drug you're still using daily. I don't know why you feel you need to use it so often, some people just do. Most people I knew stopped almost altogether at some point by the time they reached 30, but some just don't like life without it. Now, there are people who don't digest things they consume normally -- I worked for a woman who had that problem -- and sometimes if you have that condition the smell of what you eat can come out. But otherwise, the smell if you're smelling it isn't coming from "withdrawal," it's coming from the burning odor adhering to your clothes or your hair or the like. Frankly, I always used to smell like campfires because I went camping so often and the smell of the fires just stuck to my clothing. If you want to avoid that possibility, stop using it or eat it instead of smoke it.
