This is worse than KO drops because here you are not sleeping or unconscious but you lose all your inhibitions and do all the things which you never do normally.
This includes also all kinds of sexual practises. If you do anything willingly there is no punishment for your blind date partner. Leave all the used coffee cups or glasses so that the date rape drugs could be analysed and found there. That is the only evidence to punish that person.

Gamma-hydroxybutyrate (GHB) and some of the tranquilizers (benzodiazepines) are used for this purpose. These drugs have no colour or taste and so it could me mixed with any drink.

The simple rules to avoid date-rape are:

• Never accept a blind date
• Ask the person’s identity
• Be careful with your drinks
• Never empty the glasses quickly, sip slowly and then you have a chance to find out the change in your head
• When you are in his apartment or he in your apartment, ring your friend or somebody else in the family and inform them that you are with your friend or you have a visitor. This makes the visitor afraid to do any harm to you

But, prevention is the best way because these mentally sick and perverse persons are prepared to even murder you if they want to escape from such a situation, e.g. a rape.
