Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain’s own chemicals, they don’t activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.
Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This too amplifies or disrupts the normal communication between neurons.

Answer:</h3>
Change in temperature = 2.03°C, the temperature is increasing
<h3>
Explanation:</h3>
- To calculate the quantity of heat absorbed or released by a substance we multiply mass of the substance by it's specific heat capacity and the temperature change.
- Therefore, Quantity of heat, Q = mass × specific heat × change in temperature
In this case;
Mass of water = 30.0 g
Quantity of heat absorbed = 255 J
Specific heat capacity of water = 4.186 J/g°C
Rearranging the formula, Δt = Q ÷ mc
Δt = 255 J ÷ (4.186 J/g°C×30.0 g )
= 2.03 °C
The temperature change is 2.03°C, the temperature is therefore increasing.
