What's the reasoning? You're expected to report any drug activity and if you don't it's considered collusion?

Basically, yes.  Convictions are rare due to the difficulty in obtaining proof, but this is still a pretty serious accusation, especially if you are sharing a house with a drug user.  I suppose this is only an issue if the police were to actually show up, and although the risk of this is small, it's not a chance I'd recommend taking.   

There was a discussion on another forum earlier this year where guys asked if they could smoke a joint after or during the appointment. Thought it quite reasonable. Drug use is quite widenspread and convictions low. I've never heard of anyone getting in trouble for not reporting the use of Class As and I used to hang around with a group of "new-ager" free partying types.

I suspect there are lots of nicky-picky laws out there that are never used nor useable. Isn't it a Police Officers duty to report ANYONE they think are commiting a crime?So how come I've seen them walking around the corner from underage youths drinking beer and not moving on cars parked on the pavement?

Kat and Colette you are bang on with treating this like any other job, and maintaining a professional demeanor. I can't tell you how many clients I have gone out to dinner with in the beginning who would get upset because I didn't drink, or refused a line, until some more mature ladies took me in line and showed me a few tricks, The Drinking But Not Drinking Trick. Have the client pour the first glass of wine, toast and pretend to take a sip, pretend to take periodic sips. Even hold the wine in your hand as you talk, this prevents the waiters from coming up and pouring. Keep an eye on the clients glass, as it gets lower, you start to pour the wine, the man likes it, as he is being served by a beautiful woman and pretty much from that point you have control of the bottle. I try to stop them from ordering another one, as I find drunk guys more difficult to handle than the coked up ones.
The coke heads, are a different story all together, cocaine is the one drug I find turns perfectly nice men into egotistical, narcissistic jackasses! Their dicks become bigger, they are the best lover, and they can screw all night. Of course none of this is true, it is the drug unlocking the Mr. Hyde side of the personality. My favorite technique I use for the cokeheads, is distraction. Whenever I am offered a line by a client, I don't accept it, nor do I decline it, I just give them something else to focus on.

You are too hilarious...I was cracking up readin this LOL

Anyone else had an experience like this,it just struck me that if a man wants you to be out of control when on a booking then theres a reason for it and he should be avoided like a dose of the clap.

There is a client I met twice, who is actually quite known...who had insisted that I take coke with him. And he has called me 4 or 5 times and everytime he is higher than a kite which pisses me off and I tell him no. He seems to not be able to call an escort without being on coke, or vice versa. I do not like coke cause it kills my appetite (I love to eat) and in turn prevents me from being able to workout the next day. I dont mind to be around clients on coke, but I wont. We call it 'partying'. And its also annoying to sit there for a whole hour watching them play with their limp ass dicks. So boring! Fuck that, give me a drink and Im good.

Sometimes I feel slightly 'left out' by not participating (one time there were 3 guys doing coke in the penthouse) but I was already well-liquored and stood very firm on my no. I also point out that if I take any, I wont 'rise' to the occasion LOL...but even that didnt work with someone before! Most of the times they dont give me no lip about not doing drugs, I refuse to be the sterotypical prostitute, even if its in the penthouse suite!
