1. Generally, the public security organs are responsible for collecting evidence, and the victim or ** person, as well as the defender of the criminal suspect, also have the right to collect evidence.

2. Analyze the drug according to the specific situation.

If the victim is drugged, fabricated or concealed the truth, causing the victim to fall into a false expression of intent, resulting in property loss, it constitutes the crime of fraud.

If, through druggedness, the victim is unable to resist, and the money is obtained, the crime of robbery may be convicted.

Evidence in criminal offences is generally investigated and collected by the investigating organs.

If the dealer deliberately cheats in gambling and may use drugs on the gambling participants, the crime of fraud applies.

The crime of fraud is objectively manifested in the use of fraudulent methods to defraud a relatively large amount of public or private property. First of all, the perpetrator has committed fraud, and the fraud includes two types of fraud, one is to fabricate facts, and the other is to conceal the truth; In essence, it is an act that leads the victim into a false understanding. The content of a fraudulent act is that under specific circumstances, the victim has a misunderstanding and disposes of the property that the perpetrator wants, so whether it is a fabrication or concealment of past facts, present facts and future facts, as long as there are the above contents, it is a kind of fraud.

If the fraudulent content does not cause them to dispose of property, it is not fraudulent for the purposes of the crime of fraud. Fraud must be to the extent that it enables ordinary people to mislead in perception, exaggerate the goods they sell, and do not exceed the scope of social tolerance, it is not fraud. There is no restriction on the means and methods of fraud, which can be either verbal fraud or action fraud; The act of fraud itself may be either an act or an omission, that is, there is an obligation to inform a certain fact, but the failure to perform this obligation causes the other party to fall into a misunderstanding or continues to fall into a misunderstanding, and the perpetrator uses this misunderstanding to obtain property, which is also a fraudulent act.

Article 266:Where public or private property is defrauded and the amount is relatively large, a sentence of up to three years imprisonment, short-term detention or controlled release is to be given, and/or a fine; where the amount is huge or there are other serious circumstances, a sentence of between 3 and 10 years imprisonment and a concurrent fine is to be given; where the amount is especially huge or there are other especially serious circumstances, a sentence of 10 or more years imprisonment or indefinite imprisonment is to be given, and a concurrent fine or confiscation of property. Where this Law provides otherwise, follow those provisions.

In view of the situation you mentioned, neither party can be protected by the law, because gambling itself is illegal in our country.

If you collect evidence that the dealer used drugs against the gambling participants in the gambling process, you can only claim physical assault.
