The main policy Lenin used was an end to grain requisitions and instead instituted a tax (Prodnalog) on the peasants, thereby allowing them to keep and trade part of their produce. At first, this tax known was paid in kind, that is in the form of agricultural service, but as the currency became more stable in 1924, it was changed to a cash payment. This increased the peasants’ incentive to produce, and in response production jumped by 40% after the drought and famine of 1921–22.

I have heard rumors that Stalin hastened Lenin’s demise. It wouldn’t shock me.
And then Beria was the one who took care of Stalin.
