Under the Louisiana controlled dangerous substance law, the conspiracy provisions are actually in the same statute that addresses attempts, La. R.S. 40:979. The normal sentenceing range for distribution of a schedule 2 narcotic is 2 to 30 years. But, if you are accused of conspiracy to distribute a schedule 2 narcotic instead of the violaiton itself, the sentencing range is reduced to 0 to 15 years.
Please note that this is assuming that the you have no prior felony convictions. If you have a prior felony conviction and it's been less that 10 years from the final disposition of your sentence, your sentence can be enhances through the multiple offender statute (e.g. 1 prior felony - 7.5 to 30, 2 prior felony convictions - 10 to 30 years, etc.).
