Answer

To determine how many statements about cannabinoids are correct, let's analyze each statement one by one.

### Step 1: Evaluate Statement (i)
**Statement (i)**: Natural cannabinoids are obtained from the inflorescence of Erythroxylum coca.

- **Analysis**: This statement is incorrect. Natural cannabinoids, such as THC and CBD, are primarily obtained from the plant Cannabis sativa, not Erythroxylum coca, which is known for producing cocaine.

**Hint**: Remember that cannabinoids are specifically derived from cannabis plants, not coca plants.

### Step 2: Evaluate Statement (ii)
**Statement (ii)**: Marijuana, Hashish, Charas, and Ganja are obtained from the flower tops, leaves, and the resin of Papaver somniferum.

- **Analysis**: This statement is also incorrect. Marijuana, Hashish, Charas, and Ganja are derived from Cannabis sativa, while Papaver somniferum is the plant from which opiates like morphine and codeine are extracted.

**Hint**: Distinguish between cannabis and opiate-producing plants; they are different and produce different substances.

### Step 3: Evaluate Statement (iii)
**Statement (iii)**: Cannabinoids are generally taken by inhalation and oral ingestion.

- **Analysis**: This statement is correct. Cannabinoids can be consumed through various methods, including inhalation (smoking or vaping) and oral ingestion (edibles or oils).

**Hint**: Consider the common methods of consuming substances that have psychoactive effects.

### Step 4: Evaluate Statement (iv)
**Statement (iv)**: Cannabinoids have no effect on the cardiovascular system of the body.

- **Analysis**: This statement is incorrect. Cannabinoids do have an effect on the cardiovascular system, often increasing heart rate and affecting blood pressure.

**Hint**: Recall that psychoactive substances typically influence bodily systems, including the cardiovascular system.

### Conclusion
From the analysis:
- Statement (i): Incorrect
- Statement (ii): Incorrect
- Statement (iii): Correct
- Statement (iv): Incorrect

Thus, only **one statement** is correct.

### Final Answer
The number of correct statements about cannabinoids is **1**.
