Place theory, frequency theory, duplicity theory, and volley theory, have all been

Place theory, frequency theory, duplicity theory, and volley theory, have all been provided as explanations for "pitch" perception.

Pitch is the perceptual trait of a sound that relates to its recurrence. Pitch is identified with tone recurrence in unadulterated tones and to the basic in complex tones. Pitch perception enables us to arrange sounds on a melodic scale.There is fractional help for every one of Place theory, frequency theory, duplicity theory, and volley theory, showing that each of the three components assume a job in pitch observation.  

Pros:

- Addiction treatment, rehabilitation, and recovery programs could potentially be less expensive.

- In Portugal, where drugs were legalized, statistics say that addicts are more likely to find recovery in rehabilation and not jail.

Cons:

- Treatments in modern health care system will not suffice to treat a new potential influx of addicts.

- Prices are estimated to fall because of more supply, so there may be a higher increase of addiction.
